Lymphocytes correspond to white blood cells, also called leukocytes, which can be observed during microscopic examination of the urine, being quite normal when up to 5 lymphocytes are found per field or 10,000 lymphocytes per ml of urine. Because these cells are linked to the body’s defenses, an increase in the amount of lymphocytes in the urine may be seen during infection or inflammation.
The lymphocyte count in the urine is performed during the common urine test, also called a urinary summary, type I urine, or SAA, which also tests other urine characteristics, such as density, pH, the presence of compounds in abnormal amounts, such as glucose, proteins, blood, ketones, nirush, bile, crystals, or cells. Learn more about its usefulness and how urine testing is performed.
- The presence of piocytes in the urine is normally considered normal when up to 5 piocytes are found per field analyzed or 10.
- 000 piocytes per ml of urine.
- The increase in the amount of lymphocytes in the urine is called pyuria and is considered when the amount is greater than 5 lymphocytes per field.
Puria usually occurs due to inflammation, urinary tract infection or kidney problem. However, it is important that the value of lymphocytes be interpreted by the doctor with the result of other parameters released in the urine test, such as the presence of nitrite, epithelial cells, microorganisms, pH, presence of crystals and urine color, in addition to the symptoms presented by the person, so that it is possible to confirm the diagnosis and start appropriate treatment. Learn about the causes of leukocytes that rise in your urine.
Urinary tract infection occurs when microorganisms, most often bacterial, reach and cause inflammation of the urinary tract, such as the urethra, bladder, ureters, and kidneys. The amount of bacteria detected in the urine indicating a urinary tract infection is 100,000 units forming bacterial colony by mL of urine, which must be observed in uroculture.
Signs and symptoms associated with a urinary tract infection include pain or burning when urinating, frequent urination, cloudy or very fragrant urine, blood in the urine, abdominal pain, fever, and chills. Learn how to identify the main symptoms of a urinary tract infection.
In addition, signs of a urine test that indicate infection, in addition to the increase in the number of lymphocytes, are the presence of blood evidence, such as red blood cells or hemoglobin, positive nitrites or bacteria, for example.
