Leukocytosis is a condition in which the white cell count is above the normal range in the blood. [ 1 ] [ 2 ] It is frequently a sign of an inflammatory response , [ 3 ] most commonly the result of infection , but may also occur following certain parasitic infections or bone tumors as well as leukemia .
Urine cytology is a test that looks for abnormal cells in urine under a microscope. The test commonly checks for infection, inflammatory disease of the urinary tract, cancer, or precancerous conditions. It can be part of a broader urinalysis. If a cancerous condition is detected, other tests and procedures are usually recommended to diagnose ...
Because the test pad reaction is dependent on pH, false positive results can occur if the urine is highly alkaline. [60] [62] Conventional test strips are not sensitive enough to reliably detect microalbuminuria, a condition in which urine albumin levels are slightly elevated, [64] although dipsticks specialized for this measurement exist. [62]
In adults, absolute lymphocytosis is present when the lymphocyte count is greater than 5000 per microliter (5.0 x 10 9 /L), in older children greater than 7000 per microliter and in infants greater than 9000 per microliter. [1] Lymphocytes normally represent 20% to 40% of circulating white blood cells. When the percentage of lymphocytes exceeds ...
CLL is usually first suspected by a diagnosis of lymphocytosis, an increase in a type of white blood cell, on a complete blood count test. This frequently is an incidental finding on a routine physician visit. Most often the lymphocyte count is greater than 5000 cells per microliter (μL) of blood but can be much higher. [41]
A urine test is any medical test performed on a urine specimen. The analysis of urine is a valuable diagnostic tool because its composition reflects the functioning of many body systems, particularly the kidneys and urinary system , and specimens are easy to obtain. [ 1 ]
A white blood cell differential is a medical laboratory test that provides information about the types and amounts of white blood cells in a person's blood. The test, which is usually ordered as part of a complete blood count (CBC), measures the amounts of the five normal white blood cell types – neutrophils, lymphocytes, monocytes, eosinophils and basophils – as well as abnormal cell ...
