Overview
The Heparin Induced Thrombocytopenia (HIT) / Anti-Platelet Factor 4-Heparin (PF4-H) IgG Quantitative Test is a high-sensitivity chemiluminescent immunoassay (CLIA) designed to detect and quantify IgG-class antibodies directed against the platelet factor 4–heparin complex — the pathogenic driver of Type II heparin-induced thrombocytopenia. This test is the cornerstone for ruling in or excluding HIT in patients exposed to unfractionated heparin or low-molecular-weight heparin, particularly in post-surgical, cardiac, and critical care settings across UAE hospitals. يوفر هذا الفحص تشخيصاً كمياً سريعاً وموثوقاً لقلة الصفيحات المحدثة بالهيبارين.

Physician Insight & Safety Protocol
A Note from Dr. Prabhakar Reddy, DHA License: 61713011 — Specialist Hematologist:
"A positive PF4-H IgG result demands immediate clinical correlation with the 4T pre-test probability score and, where available, functional confirmatory testing. This assay's quantitative output empowers clinicians to stratify thrombotic risk, but no single laboratory value should replace sound clinical judgment at the bedside. I urge every referring physician to interpret these results within the full context of platelet trends, heparin exposure timeline, and any emerging thrombotic manifestations."
⚠️ CRITICAL SAFETY NOTICE — Do not discontinue prescribed anticoagulant or antiplatelet medication without consulting your doctor. Abrupt cessation of heparin-based therapy without alternative anticoagulation coverage may precipitate life-threatening thrombotic events, including pulmonary embolism, deep vein thrombosis, or acute limb ischemia. All medication adjustments must be supervised by a DHA-licensed Hematologist or Cardiologist.
Exclusion Criteria & Emergency Red Flags
Exclusion Criteria — Do NOT proceed with home collection if any of the following apply:
- Active, uncontrolled hemorrhage or hemodynamic instability requiring urgent hospitalization.
- Known congenital bleeding disorder (e.g., Hemophilia A/B, von Willebrand disease) without prior hematologist clearance.
- Platelet count below 20,000/µL with active mucocutaneous bleeding or any evidence of intracranial hemorrhage.
- Inability to safely access a peripheral vein due to severe burns, cellulitis, or bilateral upper extremity deep vein thrombosis.
Emergency Red Flags — Seek immediate ER evaluation if you experience:
- Acute-onset skin necrosis, purpura, or painful ecchymoses at heparin injection sites (pathognomonic for HIT with thrombosis).
- Sudden dyspnea, pleuritic chest pain, or hemoptysis — suggestive of pulmonary embolism.
- Unilateral limb swelling, erythema, and pain — concerning for acute deep vein thrombosis.
- Acute confusional state, focal neurological deficit, or seizure — may indicate cerebral venous sinus thrombosis.
- Severe epigastric or flank pain with hypotension — possible adrenal hemorrhage secondary to adrenal vein thrombosis.
Pre-Test Information & Specimen Logistics
Specimen Requirements: 3 mL whole blood collected in 1 Blue Top (Sodium Citrate) tube. Mix thoroughly by gentle inversion 5–6 times immediately after collection. Overnight fasting is preferred. A duly filled Coagulation Requisition Form (Form 15) is mandatory.
Critical Cold-Chain Protocol: Transport whole blood to the laboratory within 4 hours of venipuncture. If transport within 4 hours is not possible, prepare platelet-poor plasma (PPP) within 1 hour of collection using the following validated protocol:
- Centrifuge sample at 3,600 rpm for 15 minutes.
- Transfer supernatant to a clean plastic tube using a sterile transfer pipette.
- Centrifuge this supernatant again at 3,600 rpm for 15 minutes.
- Transfer the final supernatant (PPP) into 1 labelled, clean plastic screw-capped vial.
- FREEZE IMMEDIATELY at -20°C or below. Ship frozen on dry ice. DO NOT THAW.
Specimen Stability (PPP): Frozen at -20°C: 30 days. Frozen at -70°C: 12 months. Avoid repeated freeze-thaw cycles. Hemolyzed, icteric, or lipemic specimens may interfere with CLIA performance and will be rejected with notification via WhatsApp.

Patient FAQ & Clinical Guidance
1. What is the HIT / Anti-PF4-Heparin IgG Quantitative Test, and why has my doctor ordered it?
This test measures the precise amount of IgG antibodies targeting the platelet factor 4–heparin complex, which are the direct cause of heparin-induced thrombocytopenia — a serious drug reaction that paradoxically increases clotting risk despite lowering platelet counts. Your doctor likely ordered this test because you are receiving or have recently received heparin therapy (unfractionated or low-molecular-weight heparin) and have developed a significant drop in platelet count, typically occurring 5 to 14 days after heparin exposure. The quantitative result, combined with your clinical 4T score, helps determine whether to discontinue heparin immediately and switch to a non-heparin alternative anticoagulant such as argatroban, danaparoid, or direct oral anticoagulants.
يقيس هذا التحليل الكمية الدقيقة للأجسام المضادة من نوع IgG الموجهة ضد معقد عامل الصفائح الدموية 4 والهيبارين، وهي السبب المباشر لقلة الصفيحات المحدثة بالهيبارين. يطلب طبيبك هذا الفحص عادةً عند تلقيك علاج الهيبارين وظهور انخفاض كبير في عدد الصفائح الدموية لديك.
2. How should I prepare for this blood test, and can it be done at home in the UAE?
Overnight fasting is preferred, and you must inform your phlebotomist of all medications — especially heparin, warfarin, direct oral anticoagulants, and antiplatelet agents — as these critically influence the clinical interpretation of your results. Yes, home collection is available daily from 8 AM to 11 PM across all Emirates through our ISO-certified cold-chain mobile phlebotomy service. A DHA-licensed phlebotomist arrives at your doorstep with full cold-chain transport capability, ensuring your sodium citrate sample reaches our CLIA analyzer within the validated 4-hour stability window. You will need to complete the mandatory Coagulation Requisition Form (Form 15), which our team can assist with digitally at the time of collection.

3. What do my test results mean, and what happens next after I receive them?
A positive PF4-H IgG result indicates the presence of heparin-dependent antibodies and, when correlated with a high 4T pre-test probability score, strongly supports a diagnosis of heparin-induced thrombocytopenia requiring immediate heparin cessation and alternative anticoagulation. Your quantitative optical density (OD) value will be reported alongside a clinical interpretive comment from our DHA-licensed hematology team. A negative result carries a high negative predictive value (exceeding 95%) and effectively rules out HIT in most clinical scenarios, though rare seronegative cases exist. Regardless of your result, our telephonic post-test clinical guidance service ensures you and your referring physician receive a complete interpretation within hours of report generation.
