Normal PT/aPTT screening pattern

Interpretatie

The current PT/aPTT screening pattern is not suggestive of a screen-detectable coagulation abnormality.

Differentiële suggesties

• Compatible with no major PT/aPTT pathway abnormality on the current screen.
• Does not exclude mild factor deficiency, localized bleeding risk, platelet-mediated bleeding, factor XIII deficiency, or therapy-related effects outside PT/aPTT sensitivity.

Beperkingen

• Confidence level is high; this interpretation should be correlated with the clinical question and repeat testing history.
• Documented anticoagulant context is none; clot-based follow-up should be interpreted in that setting.
• A normal PT/aPTT screen should not be used as a stand-alone exclusion of clinically important hemostatic disease.

Aanbevolen vervolgstappen

• Correlate with the bleeding or thrombosis history before dismissing clinically important hemostatic disease.
• Review assay-specific tests only if the clinical question remains unresolved despite a normal screen.
