Preparing for your blood test

Specimen collection

  • Brave patients who like to watch their blood being taken sometimes worry that it is very dark.
    Not to worry − it’s normal! Your blood is dark because it is venous blood returning to the heart and contains very little oxygen.
    Arterial blood leaving the heart after being oxygenated in the lungs is rich in oxygen and therefore looks redder and not as dark.

    So, you have nothing to worry about! Blood is only bright red in films.

  • Before any urine test, please collect a sterile container from your doctor or our laboratory.

    General cases − mid-stream urine sample
    Please follow these steps in order:

    1. Wash your hands with soap
    2. Gently clean your genital area
    3. Open the sterile container provided
    4. Discard the first part of your urine stream in the toilet
    5. Collect your remaining urine, being careful not to touch the top edge of the container
    6. Close the container carefully and label it with your surname, first name and date of birth
    7. Drop off the sample as soon as possible at the laboratory. Beyond 30 minutes, keep it cool (between +4 °C and +8 °C)

    To help you get it right, a cartoon depicting these steps is available in the Useful documents area of our website.

    24-hour urine test
    The goal here is to collect all urine produced by the kidneys in a 24-hour period. Please follow these steps in order:

    1. When you wake up, empty your bladder and discard the first urine in the toilet
    2. From this moment, note down the time on the prescription. This is the start of the 24-hour period
    3. Use the container to collect all of your urine throughout the day and night. We recommend you keep it in a cool, dark place
    4. The next day, at the time you noted down, urinate one last time and collect the final urine
    5. Label the container with your surname, first name, date of birth and the time of the final collection noted on your prescription
    6. Bring the container to the laboratory within 24 hours after final urine collection
