Measurement of Human T-lymphotropic virus 1 antibody and Human T-lymphotropic virus 2 antibody

This test detects antibodies to human T-lymphotropic viruses (HTLV) in blood. It is used to screen donated blood or tissue for the presence of HTL viruses.

Laboratory tests may be done for many reasons. Tests are performed for routine health screenings or if a disease or toxicity is suspected. Lab tests may be used to determine if a medical condition is improving or worsening. Lab tests may also be used to measure the success or failure of a medication or treatment plan. Lab tests may be ordered for professional or legal reasons. You may need this test if you have:

• Random blood donation

Donated blood or tissue:

If this test will be performed using donated blood or tissue, ask your healthcare worker if any preparation is necessary.

Venous blood:

Before having blood collected, tell the person drawing your blood if you are allergic to latex. Tell the healthcare worker if you have a medical condition or are using a medication or supplement that causes excessive bleeding. Also tell the healthcare worker if you have felt nauseated, lightheaded, or have fainted while having blood drawn in the past.

Donated blood or tissue may be used for this test, or a sample of venous blood may be collected for this test.

Donated blood or tissue:

The healthcare worker will perform a series of tests to determine if the blood that was donated would contain the antibodies for HTLV.

Venous blood:

When a blood sample from a vein is needed, a vein in your arm is usually selected. A tourniquet (large rubber strap) may be secured above the vein. The skin over the vein will be cleaned, and a needle will be inserted. You will be asked to hold very still while your blood is collected. Blood will be collected into one or more tubes, and the tourniquet will be removed. When enough blood has been collected, the healthcare worker will take the needle out.

The amount of discomfort you feel will depend on many factors, including your sensitivity to pain. Communicate how you are feeling with the person doing the test. Inform the person doing the test if you feel that you cannot continue with the test.

Donated blood or tissue:

This test usually causes no discomfort.

Venous blood:

During a blood draw, you may feel mild discomfort at the location where the blood sample is being collected.

Donated blood or tissue:

There are no special instructions to follow after this test.

Venous blood:

After a blood sample is collected from your vein, a bandage, cotton ball, or gauze may be placed on the area where the needle was inserted. You may be asked to apply pressure to the area. Avoid strenuous exercise immediately after your blood draw. Contact your healthcare worker if you feel pain or see redness, swelling, or discharge from the puncture site.

You have the right to help plan your care. To help with this plan, you must learn about your health condition and how it may be treated. You can then discuss treatment options with your caregivers. Work with them to decide what care may be used to treat you. You always have the right to refuse treatment.
