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 DLI interface was used between 1982 and 1985 for the analysis of pesticides, corticosteroids, metabolites in horse urine, erythromycin, and vitamin B 12. However, this interface was replaced by the thermospray interface, which removed the flow rate limitations and the issues with the clogging diaphragms.
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 ]
The determination of what range to use is largely dictated by what one anticipates being in the sample while being cognizant of the solvent and other possible interferences. A MS should not be set to look for mass fragments too low or else one may detect air (found as m/z 28 due to nitrogen), carbon dioxide ( m/z 44) or other possible interference.
Reference ranges for urine tests are described below: Measurement Lower limit Upper limit Unit Urinary specific gravity: 1.003 [1] [2] 1.030 [1] [2] g/mL Urobilinogen:
Urine typically has a mild odor, but strong or unusual smells can indicate a problem. A strong ammonia scent could suggest dehydration. A foul or unusual smell could be a sign of a urinary tract ...
In urine cytology, collected urine is examined microscopically. One limitation, however, is the inability to definitively identify low-grade cancer cells and urine cytology is used mostly to identify high-grade tumors. [4] If the test detects atypical or cancerous cells, further tests may be recommended, such as cystoscopy and a CT scan.
