A Capillary Blood Sample

A capillary blood sample can be easily collected at home using the lancet and collection kit provided. Please follow these simple steps to ensure a smooth and successful sample collection:

  1. Stay Hydrated
    Make sure you’re well hydrated before taking your test — this helps improve blood flow.

  2. Wash Your Hands
    Wash your hands thoroughly with warm water and soap, then dry them completely.

  3. Warm Your Hands
    Place your hand(s) in a bowl of warm water for a few minutes to encourage good circulation. Dry your hands before proceeding.

  4. Prepare the Lancet
    Remove the cap and position the lancet on the side of your fingertip.

  5. Collect the Sample
    Press the lancet firmly to obtain a drop of blood. Use the collection tube provided to collect the sample as directed in your kit.

  6. Seal the Sample
    Secure the cap tightly on the collection tube.

  7. Post Your Sample
    Place the sealed tube in the prepaid return envelope and send it directly to our laboratory for analysis.

A Urine Sample

A urine sample can be easily collected at home using the sterile container provided in your kit. Please follow these simple steps:

  1. Prepare the Container
    Use the sterile sample container included in your kit. Avoid touching the inside of the lid or container to keep it clean.

  2. Collect a Midstream Sample
    Begin urinating, then place the container into the stream to collect your sample. Try to avoid the first and last parts of your urine flow — this ensures a cleaner, more accurate sample.

  3. Seal the Container
    Close the lid tightly to prevent any leaks during transit.

  4. Post Your Sample
    Place the sealed container into the prepaid return envelope provided and send it directly to our laboratory for analysis.
