Urinary leukocyte esterase is an enzyme within leukocytes, i.e. serine protease, and the presence of weak positivity may be the result of urinary tract infections, renal diseases, and other factors.
1. Urinary tract infection: when bacteria and other pathogens invade the urethra, causing the body to produce an inflammatory response, multinucleated leukocytes may increase, which will gather at the inflammatory foci and release a large amount of leukocyte esterase.
2. Kidney disease: for example, acute interstitial nephritis can lead to renal interstitial damage, and leukocyte esterase may also be detected in the urine.
3. Other factors: for example, urinary trichomonas infection produces some oxidizing substances, vaginal secretions lead to contamination of the urine specimen, etc., which may also lead to false-positive urine leukocyte esterase.
Urine leukocyte esterase weak positive may also have other reasons, it is recommended that patients go to the regular hospital in a timely manner, improve the examination to clarify the cause of the disease, under the guidance of the doctor to give targeted treatment or treatment.
