FibroTest and ActiTest permit the non-invasive evaluation of Hepatitis C (or B) individuals for the presence of liver fibrosis and liver inflammation, respectively. The FibroTest and ActiTest scores are calculated based on patient age, gender and concentrations of serum of y-glutamyl transferase (GGT), total bilirubin (TB), a-2 macroglobulin, haptoglobin, apolipoprotein A1 and alanine aminotransferase (ActiTest). Fibrotest and ActiTest Scores, on a scale of 0.0 to 1.0, are assigned a Metavir scale indicating the level of fibrosis or inflammation present.
Overnight fasting is preferred.
Serum should be separated from the cells as soon as possible after
visible clot formation (usually 15-30 minutes after collection).
Avoid freezing and thawing.
