In my experience, only technical artifacts shorten the partial thromboplastin time (PTT) to less than the lower limit of the reference interval. Artifacts could include partial activation of the coagulation cascade through a specimen collection error, specimen chilling, excessive incubation with the initial PTT reagent prior to adding CaCl2 solution, incorrect reagent formulation, or wrong
Partial Thromboplastin Time (PTT, aPTT)
The PTT may not be prolonged until the factor levels have decreased to 30% to 40% of normal. On the other hand, lupus anticoagulant may be present but may not prolong the PTT result. If the lupus anticoagulant (LA) is suspected, a more sensitive LA-sensitive PTT or a dilute Russell viper venom time (DRVVT) can be used to test for it.

commonly called a pro-time it is used to see how long it takes to clot, if you are taking a blood thining med or even anyting with aspirin can cause blood to thin.
Increased PT and Increased PTT
To assess the possibility of DIC, get D-dimer levels. If D-dimers are elevated, measure platelet count and fibrinogen level. Test for factors II, V, VII, and X to assess a PT prolongation.
