Spectra™ APCT, SPAT™ and APTT: How They Work Together Suggested Coagulation Testing Scheme Spectra™ APCT, SPAT™ and APTT when used together as a screening package are very effective in detecting abnormalities in the intrinsic system and platelet dysfunction.
S pectra™ APCT and SPAT™ were designed to be run together. When combined with the APTT test, they work to efficiently locate potential dysfunction in the intrinsic system and with a patient's platelets. Although it is necessary to fully investigate a coagulation disorder with all tests available to a laboratory, these three can screen for problems and cover a wider range than screening with APTT (& PT) alone.
Step 1. Run APCT Normal Intrinsic system and platelet factor 3 release normal. With a normal screen it is not always necessary to order a SPAT/ PAA or an APTT. or Abnormal Intrinsic system abnormality, platelet problem or testing error present. Repeat APCT then run APTT and SPAT™ or PAA.
Step 2. Run APTT Normal Intrinsic system normal. Check platelets by running SPAT™. or Abnormal Intrinsic system abnormality, circulating anticoagulant or testing error present.
Step 3. Run SPAT™ Normal Platelet aggregation normal. Check intrinsic factors by running APTT. or Abnormal Platelet aggregation abnormality or testing error. Consider running PAA platelet aggregometery.
