Test Overview & Methodology
The Factor XII Functional Test quantifies the enzymatic activity of coagulation Factor XII (Hageman factor) in platelet-poor plasma. This assay is indicated for patients presenting with unexplained isolated prolongation of activated partial thromboplastin time (aPTT) and for the diagnostic workup of hereditary Factor XII deficiency. The methodology employs automated photo-optical clot detection using a standardized kaolin-based activation system, ensuring reproducible and precise measurement across the clinically relevant range of 1% to 150% activity.

Physician Insight & Safety Protocols
Dr. Ajay Singh | General Practitioner | DHA Registration ID: 36234132
"Factor XII deficiency is a diagnostically subtle coagulopathy โ patients rarely present with bleeding but exhibit a consistently prolonged aPTT. The functional assay provides definitive activity quantification, which is critical for distinguishing true deficiency from lupus anticoagulant or other contact pathway inhibitors. Clinical correlation with thrombotic risk assessment and family history remains essential. I caution against any empirical anticoagulation adjustments solely based on a prolonged aPTT without complete laboratory and clinical evaluation."
โ ๏ธ Clinical Medication Advisory
Do not discontinue prescribed medications (Heparin, Warfarin, or other anticoagulants) without consulting your treating physician. Abrupt cessation may increase thrombotic events. Our pre-test information provides drug-washout guidance only after physician approval.
Exclusion Criteria & Emergency Red Flags
- Active bleeding or hematoma at venipuncture site.
- Known hypersensitivity to sodium citrate additive.
- Uncorrected severe anemia (Hb < 7 g/dL) โ requires physician clearance.
- Seek immediate medical attention if: you develop spontaneous bruising, joint swelling, or uncontrolled bleeding after sample collection.
Patient FAQ & Clinical Guidance
1. How do I prepare for the Factor XII Functional Test?
Overnight fasting is preferred. You must temporarily discontinue Heparin 24 hours and oral anticoagulants 7 days prior to collection โ only with your doctorโs written consent. A 3 mL whole blood sample in a blue-top citrate tube is required. Our VIP mobile phlebotomy service collects the specimen at your location with cold-chain transport to the laboratory.
2. What does a low Factor XII result indicate?
A decreased Factor XII activity level confirms Factor XII deficiency (Hageman trait). This condition typically does not cause spontaneous bleeding but may paradoxically elevate thrombotic risk in certain clinical contexts. Isolated aPTT prolongation without bleeding history should not delay essential surgical procedures after other coagulopathies are excluded. Our telephonic consultation service connects you with a DHA-registered physician for result interpretation within 24 hours of report delivery.
3. What is the cost and insurance coverage for this test?
The total test fee is 750 AED, inclusive of VIP mobile phlebotomy and temperature-controlled specimen transport. We accept most UAE health insurance plans; send your insurance card via WhatsApp to +971 54 548 8731 for real-time eligibility verification and direct billing where applicable.
