Wbc esterase 1+意思

WBC esterase 1+ is a term used in urine analysis to describe the presence of white blood cell esterase in urine. White blood cells (WBCs) are a type of cell in the blood that help fight infections and diseases. Esterase is an enzyme that is found in WBCs.

When a urine sample is tested, the presence of WBC esterase can indicate that there are white blood cells present in the urine. This can be a sign of a urinary tract infection (UTI) or other conditions that cause inflammation in the urinary system.

The "1+" in the term refers to the strength of the positive result. In a urine dipstick test, which is a common method of testing urine, the presence of WBC esterase can be indicated by a color change on the dipstick. The strength of the color change is used to categorize the result as negative, 1+, 2+, 3+, or 4+, with 1+ being the weakest positive result and 4+ being the strongest.

If a urine sample tests positive for WBC esterase, it may be followed up with a urine culture or other diagnostic tests to determine the cause of the infection or inflammation. Treatment may involve antibiotics or other medications, depending on the underlying cause.
