The diagnosis is based on the combination of the symptoms, as very few other diseases cause the same symptoms together. Blood tests may show elevated creatinine and urea levels (in kidney involvement), raised IgA levels (in about 50% [ 12 ] ), and raised C-reactive protein (CRP) or erythrocyte sedimentation rate (ESR) results; none are specific ...
Leukocyte esterase (LE) is an esterase (a type of enzyme) produced by leukocytes (white blood cells). A leukocyte esterase test (LE test) is a urine test for the presence of white blood cells and other abnormalities associated with infection. White blood cells in the urine can indicate a urinary tract infection (UTI). Positive test results may ...
Also, urine dipstick showing leukocytes as equal predictive value as the presence of nitrites. When both are present, the predictive value goes even higher. If the patient only has leukocyte esterase or bacteria in the urine, then dysuria may suggest that the patient probably has urethritis. [3]
Other symptoms to note: Drug rashes can be a side effect of or a reaction to a new medication; almost any medication can cause a drug rash, but antibiotics and NSAIDs are the most common culprits ...
In straightforward cases, a diagnosis may be made and treatment given based on symptoms alone without further laboratory confirmation. [4] In complicated or questionable cases, it may be useful to confirm the diagnosis via urinalysis, looking for the presence of urinary nitrites, white blood cells (leukocytes), or leukocyte esterase.

The test for leukocyte esterase is indicative and does not replace microscopic examination of urine. [19] It is normal to find up to 3 (occasionally 5) leukocytes per high power field (40X) in a urine sample, with women having slightly higher results owing to vaginal contamination. [citation needed] Higher numbers indicate urinary infection.
Bacteriuria accompanied by symptoms is a urinary tract infection while that without is known as asymptomatic bacteriuria. [1] [2] Diagnosis is by urinalysis or urine culture. [3] Escherichia coli is the most common bacterium found. [1] People without symptoms should generally not be tested for the condition. [3] Differential diagnosis include ...
Sweet syndrome (SS), or acute febrile neutrophilic dermatosis, [1] [2] is a skin disease characterized by the sudden onset of fever, an elevated white blood cell count, and tender, red, well-demarcated papules and plaques that show dense infiltrates by neutrophil granulocytes on histologic examination.
