WebThe second mechanism by which hemolysis affects test accuracy and reliability is through interference from hemoglobin itself. Due to its red color, hemoglobin absorbs light between 340–440 nm and 540–580 nm, allowing it to interfere with assays across a broad range of wavelengths. ... (AST). In the case of AST, we increase the HI threshold ... WebJan 11, 2006 · Specimens from healthy human subjects were subjected to mechanically induced hemolysis, and PT and aPTT results compared with concurrently drawn nonhemolyzed control samples. In 50 paired patient specimens, there were statistically significant differences in PT (15.8 ± 8.4 vs 16.3 ± 8.7 seconds, P < .01) and aPTT (31.6 ± …
