do i need to fast for comprehensive metabolic panel blood test
Comprehensive metabolic panel Typically, the patient fasts for ten or twelve hours before the blood is drawn for the testâ€”this is particularly important for getting a useful blood glucose measurement. CMPs are also frequently performed on nonfasting patients, but the glucose level in those cases is not as useful. The following tests are then performed:[1]
Tetrazolium chloride In the TTC assay (also known as TTC test or tetrazolium test), TTC is used to differentiate between metabolically active and inactive tissues. The white compound is enzymatically reduced to red TPF (1,3,5-triphenylformazan) in living tissues due to the activity of various dehydrogenases (enzymes important in oxidation of organic compounds and thus cellular metabolism), while it remains in its unreacted state in areas of necrosis since these enzymes have either denatured or degraded.
