The Free Dictionary defines SMAC as a trademark acronym standing for sequential multiple analysis with computer. The American Association for Clinical Chemistry describes it as a comprehensive blood test that provides multiple results using only one blood sample.
SMAC gives a computerized analysis of levels of albumin, alkaline phosphatase, bilirubin, calcium, and cholesterol. It gives the medical care provider information about certain medical conditions such as blood sugar levels and hypertension, explains the American Association for Clinical Chemistry. It lets the provider assess the effect of medicines on the kidneys and liver. Any deviations from normal values can indicate kidney and breathing problems as well as diabetes-related issues. The test is performed by drawing blood from a vein. Only one blood stick is required to test for a large number of chemical analyses.
