An expected creatinine concentration indicates that the test sample is undiluted, whereas low amounts of creatinine in the urine indicate either a manipulated test or low initial baseline creatinine concentrations. Test samples considered manipulated due to low creatinine are not tested, and the test is sometimes considered failed.
[57] [58] Not all bacteria that cause UTIs produce nitrite, and because it takes time for the chemical reaction to occur, the test is best performed on urine that has been in the bladder overnight. [59] A diet low in vegetables can lead to low nitrate levels in the urine, meaning that nitrites cannot be produced. [50]
In interventional radiology, a patient's creatinine clearance levels are all checked prior to a procedure. [citation needed] Serum creatinine is another measure of kidney function, which may be more useful clinically when dealing with patients with early kidney disease. Normal creatinine level is between 80 - 120 μmol/L. [citation needed]

Abnormal kidney function may cause too much or too little urine to be produced. The ability of the kidneys to filter protein is often measured, as urine albumin or urine protein levels, [2] measured either at a single instance or, because of variation throughout the day, as 24-hour urine tests. [citation needed]
Erythropoietin is released in response to hypoxia (low levels of oxygen at tissue level) in the renal circulation. It stimulates erythropoiesis (production of red blood cells) in the bone marrow. Calcitriol, the activated form of vitamin D, promotes intestinal absorption of calcium and the renal reabsorption of phosphate.
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 ]
Enzyme multiplied immunoassay technique (EMIT) is a common method for qualitative and quantitative determination of therapeutic and recreational drugs and certain proteins in serum and urine. [1] It is an immunoassay in which a drug or metabolite in the sample competes with a drug/metabolite labelled with an enzyme, to bind to an antibody. The ...
