Overview
The purpose of this panel is to detect specific inherited genetic variations in the Factor V Leiden, Prothrombin, and MTHFR genes that may increase the risk of developing venous thromboembolism. It is not a test for diagnosing an acute blood clot, but rather a risk-assessment tool that helps clinicians understand the underlying genetic predisposition in selected patients.

Sample Collection
No special preparation required. No fasting needed.
Method: Venipuncture
Laboratory Analysis
A qualified phlebotomist will collect about 5 mL of blood from a vein in your arm using EDTA tubes. The collection takes only a few minutes.
Report Delivery
You may resume normal activities immediately after sample collection. Apply pressure to the puncture site to reduce bruising if advised.
Timeline: Samples are accepted Monday/Thursday by 11 am, and reports are issued Wednesday/Saturday as per the laboratory schedule.

Doctor's Notes
Reviewed by Dr SULOCHANA HEMCHANDRA HOLLA — MBBS, MD (Medical Genetics) · Reg. No. 8532
"A positive genetic thrombophilia marker should always be interpreted with clinical history and family history. A DNA result alone does not automatically mean long-term anticoagulation is needed."

Understanding Your Results
Not detected
No mutation identified in the tested variants. This does not exclude the possibility of venous thromboembolism from other causes.
Detected - Heterozygous
One copy of the variant was detected. Clinical significance depends on the specific gene and the individual's personal and family history.
Detected - Homozygous
Two copies of the variant were detected. This may be associated with a higher inherited risk for certain variants, especially Factor V Leiden. Specialist consultation is recommended.
Consult a haematologist or clinical geneticist for proper interpretation of this panel. If you develop sudden leg pain, swelling, warmth, chest pain, shortness of breath, or coughing up blood, seek emergency medical care immediately.
Limitations
- ⚠This panel covers only selected genetic variants; a negative result does not exclude all inherited or acquired thrombophilias.
- ⚠The clinical significance of MTHFR variants in VTE risk is debated and should be interpreted cautiously.
- ⚠All results should be interpreted by a qualified haematologist or clinical geneticist in the context of personal and family history.
Risks & Considerations
- ●Minor bruising at the puncture site
- ●Mild bleeding
- ●Hematoma
- ●Dizziness or faintness
- ●Rare risk of infection at the venepuncture site
Interfering Factors
- ●Anticoagulant therapy does not interfere with DNA-based PCR testing.
- ●Degraded or poor-quality DNA may lead to amplification failure.
