HTLV I+II Test
An HTLV I+II test screens for antibodies against Human T-Lymphotropic Virus types 1 and 2. These retroviruses can infect T-cells and, in some cases, may be associated with serious conditions such as adult T-cell leukaemia or HTLV-associated myelopathy.

Check your own valueHTLV I+II: what this test measures
This test detects antibodies against HTLV-1 and HTLV-2 in your blood. HTLV-1 and HTLV-2 are retroviruses that integrate into the DNA of T-lymphocytes. The test provides a qualitative result indicating whether antibodies to either virus type are present, which suggests past or current infection.
HTLV I+II: why this value matters
HTLV-1 infection may be associated with adult T-cell leukaemia/lymphoma and HTLV-associated myelopathy/tropical spastic paraparesis. HTLV-2 is generally considered less pathogenic but may be associated with neurological conditions. Most infected individuals remain asymptomatic, making screening important for at-risk populations and blood supply safety.
HTLV I+II: how the blood test works
- Referral
- No GP referral needed. After the order we arrange the referral through ZorgDomein, within one business day; orders after 17:00 or at the weekend start on the next business day. ZorgDomein emails a barcode, and that barcode is what the draw site needs.
- The draw
- A blood draw from a vein in the arm, at a partner laboratory's draw site. No home kit, no finger prick.
- Which test
- on its own €49,-
- Where
- 650+ draw sites run by independent laboratories across the Netherlands. Draw sites
HTLV I+II: when is testing worthwhile?
Testing may be recommended for blood and organ donors, individuals from endemic regions, or those with risk factors for HTLV infection. It may also be considered when evaluating unexplained neurological symptoms or certain haematological conditions. Consult a healthcare professional for guidance.
HTLV I+II: lifestyle and this value
Maintain a healthy immune system through regular exercise, a balanced diet, adequate sleep, and stress management. If you are at risk for HTLV, avoid sharing needles and practise safe behaviours. Consult a healthcare professional if you have concerns about your HTLV status.
HTLV I+II: frequently asked questions
What is the difference between HTLV-1 and HTLV-2?
HTLV-1 is more commonly associated with serious conditions such as adult T-cell leukaemia and HTLV-associated myelopathy. HTLV-2 is generally considered less pathogenic but may be linked to mild neurological conditions. Both viruses are transmitted through similar routes. Consult a healthcare professional for detailed information.
Can HTLV be cured?
There is currently no cure for HTLV infection. However, the majority of infected individuals never develop symptoms. Regular monitoring by a healthcare professional can help manage any complications that may arise.
