FAQs
A set of tests (commonly PT/INR and aPTT) that assess blood clotting pathways.
No.
INR standardizes PT and is used to monitor warfarin therapy and assess clotting status in certain conditions.
It assesses the intrinsic/common pathway and may be prolonged due to factor issues or certain anticoagulants.
They may affect results variably; disclose all anticoagulants for proper interpretation.
Citrate plasma (blue-top tube) collected with proper fill.
Often same day or within 24 hours.
Yes in many serviceable areas.
To assess bleeding risk and clotting status when clinically indicated.
Contact your clinician urgently; high INR can increase bleeding risk.
Yes. The liver makes many clotting factors; clinicians interpret with liver function tests.
Do not stop medicines unless instructed by your clinician.

For uncontrolled bleeding, severe headache/weakness, black stools, or stroke-like symptoms, seek emergency care.
Notes
Coagulation panels must be interpreted by clinicians.
