Web4 mei 2024 · The correlation between Hepcon and i-STAT activated clotting time (ACT) results was 0.94. The i-STAT ACT results were generally 23 seconds lower than the Hepcon ACT values. Correlation coefficients on comparing Hepcon ACT and i-STAT ACT using laboratory anti-Xa assay were 0.83 and 0.87, respectively. The typical reference range is between 25 seconds and 33 s (depending on laboratory). Longer times of up to 50 s do apply to infants. Shortening of the PTT is considered to have little clinical relevance, but some research indicates that it might increase risk of thromboembolism. Normal PTT requires the presence of the following coagulation factors: I, II, V, VIII, IX, X, XI and XII. Notably, deficiencies in factors VII or XIII will not be detected with the PTT test.
