What's this test for?

This test is ideal if you've been potentially exposed to HTLV through sexual contact, needle sharing, or blood transfusion and want to know your status. It helps detect infection with human T-lymphotropic virus (HTLV-I or HTLV-II), which can cause serious health issues including T-cell leukemia, lymphoma, and neurological problems, though many people remain asymptomatic for years. It's particularly important if you have unexplained symptoms like weakness, muscle problems, or frequent infections, or if you're at higher risk due to specific exposures.

What happens after I get my results?

You'll receive detailed doctor notes in simple language explaining what your HTLV test results mean for your health status. If positive, the notes include specific guidance on follow-up confirmatory testing, monitoring recommendations, and preventive measures to protect partners and family members. You'll also get the standard lab report, and if you're monitoring a known infection, you can track your results over time using our trends feature to ensure proper management.

What's included in this test?

This test measures HTLV I/II Antibody with Reflex Confirmatory Assay. This test measures HTLV I/II antibodies in your blood using a preliminary screening assay, and if positive, automatically performs confirmatory testing to distinguish between HTLV-I and HTLV-II infection. The two-step process ensures accurate diagnosis by first detecting any HTLV antibodies present, then confirming which specific virus type you may have been exposed to. This comprehensive approach minimizes false positives and provides definitive results to guide appropriate medical follow-up and care.

How should I prepare for this test?

No special preparation is typically required for this HTLV antibody test. You can eat and drink normally before your blood draw, and you don't need to fast. However, it's important to note that if you were recently exposed to HTLV, it may take several weeks to months for antibodies to develop and become detectable, so timing of the test matters for accurate results.

When will I get my results?

Results are typically available within 5-7 business days for negative preliminary screening tests. If the preliminary test is positive, confirmatory testing will be performed automatically, which may extend the turnaround time to 7-10 business days to ensure accurate identification of the specific virus type. You'll be notified as soon as your complete results are ready.

Who should consider getting this test?

This test is important for anyone with potential HTLV exposure through unprotected sexual contact, past intravenous drug use with shared needles, or blood transfusions received before screening protocols were established. It's also recommended for people from or who have lived in areas where HTLV is more common (parts of Japan, Caribbean, South America, Africa), those with unexplained neurological symptoms or blood disorders, pregnant women in high-risk groups, and sexual partners of HTLV-positive individuals.

What symptoms indicate I may need this test?

Many people with HTLV have no symptoms for years or decades. However, you should consider testing if you experience progressive leg weakness, muscle stiffness, difficulty walking, bladder or bowel problems, frequent infections, unexplained skin lesions, or swollen lymph nodes. Some people develop vision problems, numbness, or tingling in the limbs. Since symptoms can take decades to appear after infection, testing based on risk factors rather than symptoms is often more appropriate.

What is HTLV and why does it matter?

Human T-lymphotropic virus (HTLV) is a retrovirus that infects T-cells, a crucial part of your immune system. While most infected people never develop symptoms, HTLV-I can cause adult T-cell leukemia/lymphoma or a progressive neurological condition called HTLV-associated myelopathy. HTLV-II is less understood but may cause similar issues. The virus spreads through sexual contact, blood exposure, and from mother to child, making early detection important for preventing transmission to others.

What does a positive HTLV result mean?

A confirmed positive result means you have antibodies to HTLV-I or HTLV-II in your blood, indicating current infection with the virus. While this doesn't mean you'll definitely develop disease (most infected people remain healthy), it does mean you can transmit the virus to others and should take precautions. You'll need regular medical monitoring, should avoid donating blood or organs, practice safe sex, and if you're a woman planning pregnancy, discuss the risks of mother-to-child transmission with your doctor.

How can I prevent HTLV transmission if I'm positive?

If you test positive for HTLV, always use condoms during sexual activity to protect partners, never share needles or drug equipment, and don't donate blood, plasma, organs, or sperm. Women who are HTLV-positive should discuss infant feeding options with their doctor, as the virus can be transmitted through breastfeeding. It's also important to inform healthcare providers of your status before any procedures and to notify current and past sexual partners so they can get tested.

How often should I retest for HTLV?

If you test negative but had a recent high-risk exposure, you should retest in 3-6 months, as it can take time for antibodies to develop (window period). If you're negative and remain at ongoing risk, annual testing may be appropriate. If you test positive, you don't need to retest for HTLV antibodies since the infection is lifelong, but you will need regular medical monitoring with blood counts and other tests to watch for any disease development.
