Reptilase time is relatively insensitive to which interfering agent?

Explanation:
Heparin is a common interfering agent that prolongs tests dependent on thrombin. Reptilase time uses reptilase to convert fibrinogen to fibrin, bypassing thrombin, so its result isn’t significantly affected by heparin. In contrast, thrombin time directly relies on thrombin and is prolonged by heparin, and PT and aPTT can also be influenced. Because reptilase time remains relatively stable in the presence of heparin, it’s the test that best resists this interference.
