Normal urine pH is slightly acidic, with usual values of 6.0 to 7.5, but the normal range is 4.5 to 8.0. A urine pH of 8.5 or 9.0 is indicative of a urea-splitting organism, such as Proteus, Klebsiella, or Ureaplasma urealyticum; therefore, an asymptomatic patient with a high pH means UTI regardless of the other urine test results.
Measurement Lower limit Upper limit Unit Urinary specific gravity: 1.003 [1] [2]: 1.030 [1] [2]: g/mL Urobilinogen: 0.2 [2]: 1.0 [2]: Ehrlich units or mg/dL : Free catecholamines, dopamine ...
5-HIAA is the major urinary metabolite of serotonin, a ubiquitous bioactive amine. Serotonin, and consequently 5-HIAA, are produced in excess by most carcinoid tumors, especially those producing the carcinoid syndrome of flushing, hepatomegaly (enlarged liver), diarrhea, bronchospasm, and heart disease. Quantitation of urinary 5-HIAA is the ...
They only find out they have a heart condition after experiencing a heart attack or heart failure, or when heart disease is diagnosed on a test like an echocardiogram or cardiac stress test.
Urinalysis, a portmanteau of the words urine and analysis, [1] is a panel of medical tests that includes physical (macroscopic) examination of the urine, chemical evaluation using urine test strips, and microscopic examination.
The pH of urine normally vary between 4.5 and 8 with the first urine produced in the morning generally being more acidic and the urine produced after meals generally more alkaline. [4] Normal reference values are not provided for urine pH as the variation is too wide and results have to be considered in the context of the other quantifiable ...
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] Common urine tests include the routine urinalysis, which examines the physical, chemical, and microscopic properties of the urine; urine ...
Urinalysis is a test that studies urine for abnormal substances such as protein or signs of infection. [35] A Full Ward Test , also known as dipstick urinalysis, involves the dipping of a biochemically active test strip into the urine specimen to determine levels of tell-tale chemicals in the urine.
