🎁ESR
ESR (Erythrocyte Sedimentation Rate) is a blood test that measures how quickly red blood cells settle to the bottom of a test tube. It is not a specific diagnostic test for any condition, but it is an indicator of inflammation in the body as a whole.
Here are some common cases where an ESR may be requested.
1. Inflammatory conditions:
• Rheumatoid arthritis: ESR is often elevated in people with rheumatoid arthritis, a chronic autoimmune disease that causes inflammation in the joints.
• Systemic Lupus Erythematosus (SLE): Another autoimmune disease, SLE can cause inflammation throughout the body, including the joints, skin, kidneys, and heart.
• Inflammatory bowel disease (IBD): Conditions such as Crohn's disease and ulcerative colitis involve chronic inflammation of the digestive tract, leading to elevated ESR.
• Temporal Arthritis (Giant Cell Arthritis): An inflammatory condition that affects the arteries, often causing headaches, jaw pain, and vision problems.
2. Infections;
• Bacterial Infections: ESR may be elevated in bacterial infections, especially serious diseases such as pneumonia, septicemia, and endocarditis.
• Tuberculosis: Active tuberculosis can cause a significant increase in ESR.
Important Notes:-
• ESR is a non-specific test, meaning that a high ESR does not necessarily indicate a specific disease.
• May be affected by factors such as age, gender and pregnancy.
• Other tests, such as blood tests for certain markers or imaging studies, are usually necessary to confirm the diagnosis.
• A normal ESR does not rule out the presence of inflammation or disease.
