Hepatitis B Virus (HBV) HBV-DNA detection by PCR

The Hepatitis B Virus (HBV) HBV‑DNA detection by PCR is a molecular test that identifies and quantifies HBV genetic material in the bloodstream using sensitive real‑time PCR technology. It provides a viral load result (typically reported in IU/mL) that indicates active viral replication, helping to diagnose infection status and measure disease activity. The high analytic sensitivity enables detection of low‑level viraemia, making it valuable for early diagnosis and for monitoring response to antiviral therapy. Home sample collection is available across Dubai and the UAE for convenient, confidential testing with samples processed in accredited laboratories.

This test is primarily used to establish a baseline viral load after a positive HBsAg result, to guide initiation of antiviral treatment, and to monitor treatment efficacy or detect virologic breakthrough. It is recommended for pregnant women who are HBsAg positive (to assess transmission risk), patients undergoing immunosuppressive therapy or chemotherapy, and individuals being evaluated for liver transplant or antiviral management. Results should be interpreted alongside clinical findings and liver function tests by a physician; follow-up testing frequency is determined by the treating clinician and treatment plan.

• HBV‑DNA (Quantitative) — Viral load (IU/mL)
• HBV‑DNA (Qualitative) — Detected / Not detected
• Assay sensitivity / Lower limit of detection

• At diagnosis after positive HBsAg to determine baseline viral load
• When abnormal liver function tests suggest active hepatitis B
• Regular monitoring during antiviral therapy to assess response
• Before starting immunosuppressive therapy, chemotherapy or biologics
• During pregnancy if HBsAg positive to evaluate transmission risk

• Quantitative viral load to guide treatment initiation and monitoring
• High sensitivity real‑time PCR detects low-level viraemia
• Home blood collection across Dubai and the wider UAE for convenience
• Confidential, clinician-ready reports with timely turnaround
• Supports pregnancy management, pre-transplant evaluation, and resistance detection

• Venous blood sample (EDTA plasma) collected at home by trained phlebotomist
• No fasting required unless combined with other tests
• Provide Emirates ID and any relevant prescription or clinical notes
• Inform collector about current antiviral medications and recent vaccinations
