The immunoassay method that directly labels antibodies or antigens with chemiluminescence agents is called chemiluminescence immunoassay, which has both high sensitivity of chemiluminescence and high selectivity of immunoassay.
Compared with other immune diagnostic techniques, chemiluminescence immunoassay has the advantages of strong specificity, high sensitivity, rapidity, quantifiability, wide detection range, and high degree of automation, gradually replacing enzyme-linked immunosorbent assay as the mainstream technology for immune diagnosis. In the high-throughput immunodiagnosis market, chemiluminescence method will occupy over 85% of the market share in 2022, with a market size exceeding 7 billion USD.
The chemiluminescence immunoassay technology is divided into three platforms based on the luminescence principle and different markers: enzymatic chemiluminescence, direct chemiluminescence, and electrochemiluminescence. Different platforms have different technical advantages. The electrochemiluminescence market is mainly dominated by Roche, and in the past two years, due to the expiration of patent protection period, some manufacturers have also launched electrochemiluminescence. In addition to electrochemiluminescence, manufacturers have the choice of direct chemiluminescence and enzymatic chemiluminescence platforms represented by acridine ester (AE) and alkaline phosphatase (AP), respectively.
The biggest difference between AP and AE chemiluminescence is that alkaline phosphatase catalyzes substrates such as AMPPD to emit light, belonging to the glow type (entering the luminescence plateau period and continuously emitting light); acridine ester emits light directly through hydrolysis under the action of hydrogen peroxide and hydroxide ions, belonging to the flash type (the luminescence value enters the highest value at around 0.5s and ends within 1s). Therefore, direct chemiluminescence of acridine ester requires higher instrument requirements, requiring in-situ addition of excitation solution and completion of reading within 1s, but the faster it is, the stability may be affected. The disadvantage of alkaline phosphatase is that the enzyme and substrate need to be incubated and reacted for a period of time before the luminescence value can reach the plateau. Although the result time may be longer than AE, it is relatively more stable.
In fact, there is no single chemiluminescence technology that can be absolutely superior to others in direct chemiluminescence, enzymatic chemiluminescence, and electrochemiluminescence. For users, what is more important is the manufacturer's mastery of these core technologies and the overall solutions they provide. These factors collectively determine whether the system can operate stably and efficiently, and ultimately affect the accuracy and reliability of the detection results. In addition, the compatibility and matching between reagents and instruments are also important aspects that cannot be ignored. Good matching can ensure the consistency of the entire analysis process, thereby improving experimental efficiency and data quality.
As a professional manufacturer in the field of chemiluminescence, Rayto has Its own R&D center in Shenzhen and Hunan, as well as a complete and strict quality control system. The instruments and reagents are self-developed and produced independently, achieving a high degree of matching between reagents and instruments, further enhancing the overall performance of the system.

October 13, 2024 is the 11th World Thrombosis Day, aimed at raising public awareness of thrombotic diseases and further reducing the occurrence and harm of venous thrombosis through education and awareness raising.
The formation of blood coagulation is usually related to the following factors:
1. Vascular injury: Vascular injury is an important cause of thrombosis, such as surgery, trauma, burns, etc. These factors can damage endothelial cells, causing platelets and fibrin to aggregate at the damaged site and form blood clots. 2. Increased blood coagulation: Increased blood coagulation means that blood is prone to forming blood clots. For example, factors such as an increase in platelet count and fibrinogen content in the blood can lead to an increase in blood clotting. 3. Slow blood flow: Long term sitting, bed rest, and other unhealthy habits may lead to slow blood flow, providing conditions for thrombus formation. For example, patients who travel by plane, car, or bed for a long time are prone to developing deep vein thrombosis in the lower limbs.
2. Pay attention to the risk of thrombosis. After any part of the body's blood vessels become blocked, it can cause organ damage, resulting in insufficient blood supply to related organs, leading to serious consequences and even sudden death. Thrombosis can form in the blood vessels of the brain, leading to cerebral infarction (stroke); If it occurs in the coronary artery, it may lead to myocardial infarction (MI); Once the pulmonary blood vessels are blocked, it may lead to fatal pulmonary embolism... These diseases closely related to blood clots, such as myocardial infarction, cerebral infarction, lower limb vascular disease, etc., are all serious threats posed by blood clots to the human body. Venous thromboembolism (VTE): VTE includes pulmonary embolism (PE) and deep vein thrombosis (DVT), which mainly occur due to factors such as slow venous blood flow, venous vessel damage, and increased blood coagulation, leading to abnormal coagulation of blood in the veins and the formation of thrombi. Venous vessels are completely or partially blocked, affecting normal blood circulation. VTE is also the world's third largest cardiovascular disease after ischemic heart disease and stroke. Because of its high incidence rate, hidden symptoms and high mortality, it is known as the "silent killer". Therefore, it is particularly important to prevent thrombosis, detect thrombosis in a timely manner, and take measures to treat thrombosis.
The important role of D-Dimer&FDP combined application in preventing VTE
1. Thrombosis exclusion/diagnosis and dynamic monitoring: ① Deep vein thrombosis and pulmonary embolism (early exclusion diagnosis, low to moderate clinical likelihood population), when D-dimer&FDP negative, the risk of thrombosis can be temporarily ruled out; ② Early diagnosis and dynamic monitoring of DIC; ③ Identification of cerebral infarction.
2. Thrombolytic therapy monitoring and evaluation (VTE anticoagulant therapy monitoring) showed a significant increase in D-dimer and FDP under the action of thrombolytic drugs. When the thrombus was completely dissolved, D-dimer and FDP in the plasma rapidly decreased and returned to normal after 2 weeks. Therefore, dynamic detection of D-dimer and FDP concentration changes has significant clinical value in monitoring the efficacy and safety of thrombolytic drugs.
3. Monitoring of Thrombosis Risk and Assessment of Disease Condition (Determination of Fibrinolytic Hyperactivity)

September 29, 2024 is the 25th World Heart Day, and this year's theme is "USE HEART, FOR ACTION", emphasizing the importance of heart health and positive action. The heart is one of the most significant organs in the human body, like an tireless pump that constantly delivers blood to the body day and night, maintaining the normal functioning of life. Heart health is directly related to the normal physiological function of all organs in the body and the maintenance of life activities, so it is crucial to pay attention to heart health. When sudden chest tightness, chest pain, unexplained palpitations, shortness of breath or fatigue, unexplained sweating, nausea and other cardiac discomfort symptoms occur, it is necessary to seek medical attention promptly for corresponding examinations in order to diagnose heart problems early and take intervention measures timely .
There are multiple examination techniques for heart disease
Cardiac ultrasound: mainly through color Doppler ultrasound examination, it can more accurately observe the structure and morphology of the heart.
Coronary angiography: By puncturing the arm or thigh artery and injecting contrast agent, the image of the coronary artery is observed to assist in the examination of heart disease.
Electrocardiogram examination: It can detect cardiac abnormalities through 24-hour dynamic electrocardiogram or exercise stress test.
Laboratory examination: Blood tests are required for heart disease patients, including blood routine, liver and kidney function, blood lipids, blood glucose, myocardial enzymes, electrolytes, B-type natriuretic peptide, troponin, myoglobin, D-dimer, etc. The specific items that need to be tested are selected based on the type and severity of the heart disease, usually in combination with imaging and other techniques. In clinical practice, in order to clarify the diagnosis of a certain disease, it is generally necessary to coordinate multiple examinations and select the appropriate approach based on the patient's chief complaints, symptoms, and other factors, in order to achieve early detection, diagnosis, treatment, and recovery.
The Rayto Chemray series and Lumiray fully automatic biochemical analyzer have characteristics of high automation, stable operation, and superior performance. We have a complete combination of cardiac solution, which can provide the best diagnostic solution for clinical practice, ensuring accurate, fast, and high-performance testing results.

Why more and more companies combine the CRP with WBC?

The Detection of WBC has already been the basic diagnostic method around the world. But with the improvement of medical technology, people find out that the wide range of the WBC could not reflect the dynamics of the disease greatly, moreover, the result of WBC only would be affected by plenty of factors, such as the age, body resistance, drug treatment, it might bring some influence of the diagnostic and treatment of patients.
While the detection of CRP would provide quick response to the acute inflammation, could help to identify the type of infection, reflects the course of the disease well. Therefore more and more companies combine the CRP with the WBC, so as Rayto. Rayto launch the 5-diff hematology analyzer Hemaray 50 CRP also and up-coming module Hemaray 90, combine the basic blood diagnostic with the CRP, help clinic,hospital to make the more accuracy result, provide more suitable treatment.

What is Anti-Mullerian Hormone (AMH)?
AMH, or Anti-Mullerian hormone, is a hormone that is made by granulosa cells that take care of the eggs, so the more eggs a woman has, the more granulosa cells she has, and the higher her AMH. We like to use AMH as a marker of a woman’s overall egg count.

The nitty-gritty details about AMH
AMH or anti-mullerian hormone is a substance produced by granulosa cells in ovarian follicles.
It is first made in primary follicles that advance from the primordial follicle stage. At these stages, follicles are microscopic and cannot be seen by ultrasound.
AMH production is highest in preantral and small antral stages (less than 4mm diameter) of development.
Production decreases and then stops as follicles grow. Almost no AMH made in follicles over 8mm.
Therefore, the levels are fairly constant and AMH testing can be done on any day of the woman’s cycle.

What does AMH mean in regards to your fertility?
AMH is an important fertility test to tell us about a woman’s ovarian reserve as it stands today. Higher AMH values (greater than 1 ng/mL) usually signify that a woman has a normal ovarian reserve. Lower numbers (less than 1 ng/mL) may indicate a woman with diminished ovarian reserve (DOR).

We know that a woman’s fertility declines as she ages so typically we see AMH values also start to decline as women age. The value of this test is that a woman with a low AMH can choose to do something about her fertility now if she desires a family for the future.

How can an AMH blood test help diagnose infertility?
Since AMH is produced only in small ovarian follicles, blood levels of this substance have been used to attempt to measure the size of the pool of growing follicles in women.

Research shows that the size of the pool of growing follicles is heavily influenced by the size of the pool of remaining primordial follicles (microscopic follicles in “deep sleep”).
Therefore, by reading the levels of an AMH blood test a fertility doctor can determine the size of the remaining egg supply – or “ovarian reserve.”

With increasing female age, the size of their pool of remaining microscopic follicles decreases. Likewise, their blood AMH levels and the number of ovarian antral follicles visible on ultrasound also decrease.

Women with many small follicles, such as those with polycystic ovaries (PCOS) have high AMH hormone values. Women that have few remaining follicles and those that are close to menopause have low anti-mullerian hormone levels.

Malaria is one of the most serious tropical insect-borne infectious diseases in the world, with high incidence rate and mortality. Malaria is spreading in different regions, often bringing economic challenges and medical costs. Malaria, HIV / AIDS and tuberculosis are recognized as the three most serious public health problems in the world, and the number of people who die of malaria every year has exceeded that of AIDS.

Plasmodium is a kind of single celled and parasitic protozoa. There are two hosts, human and mosquito, which can reproduce sexually in the parasite and asexually in the human body. Anopheles mosquitoes carrying Plasmodium transmit the malaria parasite by biting people. The malaria parasite first passes through the liver cells (extraerythrocytic phase) and then enters the erythrocytic development (intraerythrocytic phase) in the human body, The content of DNA and RNA in the parasitized red blood cells gradually increases, and the volume of infected red blood cells is also changing. The main cause of clinical symptoms is plasmodium in the red blood stage. During malaria infection, patients will have obvious fever, and organs will be involved to varying degrees, leading to local or systemic damage, but also causing hematological changes.
Blood cell count is a routine test item for patients with fever. The study found that the use of digital and image results in blood analyzers could help to screen for malaria. At present, all blood cell analyzers cannot directly detect malaria parasites, but further microscopic examination of blood smear can be carried out on blood samples according to the abnormal alarm information provided to determine whether malaria parasites are infected. Although this method requires the examiner to carefully observe the figures and data, the software analysis technology can increase the probability of screening malaria parasites. There is a significant difference between the WBC of malaria patients and that of ordinary fever patients. When Plasmodium parasitizes in red blood cells, a large number of red blood cells are destroyed after maturity, and the phagocytosis of macrophages leads to the reduction of red blood cells, which makes the patient appear anemia symptoms. The fragments of red blood cells destroyed by malaria parasites and the metabolites of malaria parasites pierce the body, causing congestion and swelling of the liver and spleen, leading to hypersplenism, and significantly reducing the number of macrophages. The RBC, HGB, RDW and PLT of malaria patients are significantly different from those of normal physical examiners. The results of most malaria patients are not high, and there are low RBC, HGB and PLT, as well as the changes of white blood cells, especially monocytes and lymphocytes caused by confusion. All of these suggest that these changes can be closely related to malaria cases. A blood cell analyzers can provide the above parameters.
However, at present, there have been many breakthroughs in malaria diagnosis technology, but finding plasmodium by microscopic examination is still the "gold standard" for malaria etiology diagnosis. In clinical practice, "blood routine examination for malaria parasites" is still the most common examination mode for suspected malaria patients. Therefore, it is of important reference value to pay attention to the analysis of blood cell parameters, understand the change rules of blood cell parameters, and prevent misdiagnosis and missed diagnosis.
