During a urinalysis, several components of the urine are examined.
Physical Characteristics: The color, clarity, and odor of the urine can provide initial clues about a
person's hydration status and potential health issues.
Chemical Analysis: This involves testing for the presence of various substances in the urine, including glucose (sugar), ketones, proteins, nitrites, and leukocytes (white blood cells). Abnormal levels of these substances can indicate conditions like diabetes, kidney disease, or urinary tract infections.
Microscopic Examination: Under a microscope, the urine sample is examined for the presence of red blood cells, white blood cells, bacteria, crystals, and other cellular elements. This can help diagnose urinary tract infections, kidney stones, and other disorders.
pH Level: The pH level of the urine indicates how acidic or alkaline it is. Normal urine pH is around 6.0 to 7.5. Abnormal pH levels can be indicative of metabolic conditions or dietary factors.
Specific Gravity: This measures the concentration of dissolved particles in the urine, which reflects how well the kidneys are regulating water balance. High specific gravity can be a sign of dehydration or kidney problems.
Protein Levels: Detecting protein in the urine can indicate kidney damage or dysfunction.
Glucose and Ketones: Presence of glucose in the urine may suggest high blood sugar levels, potentially indicating diabetes. Ketones in the urine can indicate a state of ketosis, often seen in uncontrolled diabetes or low-carbohydrate diets.
Nitrites and Leukocytes: Their presence suggests a urinary tract infection, as these substances can be produced by certain bacteria.
Urinalysis is often performed as a part of routine medical check-ups, pre-employment screenings, pregnancy care, and when symptoms like frequent urination, pain during urination, or unusual urine color are present. The results of a urinalysis can provide valuable information to healthcare professionals, helping them diagnose and monitor various conditions.
