About the product
PHOS2 (Phosphate (Inorganic) ver.2) is an in vitro diagnostic reagent from Roche Diagnostics for the measurement of inorganic phosphate. According to Roche’s product page, the test is used on cobas c systems for the quantitative determination of phosphorus in human serum, plasma and urine.
The product is part of the Roche Diagnostics test kit range supplied by Tilia Medical.
Roche words the intended use slightly differently by analyzer group. For the cobas c 111, inorganic phosphate concentration is mentioned; for cobas c systems, phosphorus. The cobas c 111 pack appears on the page as Phosphor 100T.
Measured parameter and clinical significance
Phosphate is an electrolyte containing the mineral phosphorus that helps regulate fluid balance and pH. According to MedlinePlus, most of the body’s phosphate is found in bones, combined with calcium.
The blood phosphate test is used, mostly together with other tests, in the diagnosis or monitoring of kidney diseases, chiefly chronic kidney disease, of bone and parathyroid disorders, of poorly controlled diabetes and of acid-base imbalances. It may also be requested when a calcium result is abnormal. MedlinePlus notes that a physician may request a urine phosphate test instead of, or in addition to, the blood test.
