Test strips contain pads impregnated with chemical compounds that change color when they interact with specific elements in the sample, such as glucose, protein and blood, [10] and microscopic examination permits the counting and classification of solid elements of the urine, such as cells, crystals, and bacteria.
Serum total protein, also known as total protein, is a clinical chemistry parameter representing the concentration of protein in serum. [1] Serum contains many proteins including serum albumin, a variety of globulins, and many others. While it is possible to analyze these proteins individually, total protein is a relatively quick and ...
Protein dipstick measurements should not be confused with the amount of protein detected on a test for microalbuminuria which denotes values for protein for urine in mg/day versus urine protein dipstick values which denote values for protein in mg/dL. That is, there is a basal level of proteinuria that can occur below 30 mg/day which is ...
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.
Concentrated nitric acid is added to a protein solution from the side of the test tube to form two layers. A white ring appears between the two layers if the test is positive. [1] Heller's test is commonly used to test for the presence of proteins in urine. [2] This test was discovered by the Austrian Chemist, Johann Florian Heller (1813-1871).

FD&C Red No. 40, more commonly known as red 40, is making headlines again as lawmakers debate whether food dyes should remain legal in the United States.. The dye, which has been registered with ...
Serum protein electrophoresis (SPEP or SPE) is a laboratory test that examines specific proteins in the blood called globulins. [1] The most common indications for a serum protein electrophoresis test are to diagnose or monitor multiple myeloma , a monoclonal gammopathy of uncertain significance (MGUS), or further investigate a discrepancy ...
