    What does a blood test for weight management show?

    Cholesterol (lipid profile) — 7 biomarkers

    Cholesterol is an essential fat that your body produces. It helps make vitamin D and hormones. Your body needs cholesterol to stay healthy, but too much can increase your risk of heart disease. The cholesterol home test, also called a lipid profile test, measures the different types of fats in your blood. 

    The cholesterol home test checks 7 biomarkers:

    • LDL (low-density lipoproteins)
    • Non-HDL cholesterol (bad cholesterol)
    • HDL (good cholesterol)
    • Total cholesterol
    • Triglycerides
    • Total cholesterol: HDL ratio
    • Triglycerides: HDL ratio 

    High cholesterol has no symptoms, so regular testing is the only way to keep track of your levels.

    Healthy levels of cholesterol:

    • Total cholesterol - below 5mmol/L
    • HDL (good cholesterol) - above 1.0mmol/L for men or above 1.2mmol/L for women
    • Non-HDL (bad cholesterol) - below 4mmol/L
    • LDL: below 3mmol/L
    • Triglycerides: less than 1.7mmol/l (after fasting for 12 hours); less than 2.3 (non-fasting)
    • Triglycerides: HDL ratio - There are no widely accepted normal values for the TG:HDL ratio. Generally, the lower your result the better.

    HbA1c (diabetes risk) — 1 biomarker

    An HbA1c test measures your average blood sugar (glucose) levels over the past 3 months. This can help you understand your risk of developing type 2 diabetes or pre-diabetes.

    When the amount of sugar in your blood rises, any that your body can’t use attaches to red blood cells to form glycated haemoglobin (HbA1c).

    Red blood cells live for around 3 months, which is why a HbA1c test measures the average blood sugar over the past few months.

    The at-home HbA1c test will show you whether you have healthy levels of HbA1c.

    Results include: 

    NormalBelow 42 mmol/mol
    Prediabetes
    42 to 47 mmol/mol
    Diabetes48 mmol/mol or over


    Thyroid function — 2 biomarkers

    The thyroid is a gland at the front of your neck that produces hormones (T3 and T4).

    If it becomes underactive, it may not release the right levels of these hormones. This can result in symptoms such as weight gain and fatigue.

    The at-home thyroid blood test checks levels of free thyroxine (T4) and thyroid-stimulating hormone (TSH), which regulates the release of thyroid hormones.

    Healthy ranges include:

    • Free T4 between 12-22 pmol/L
    • TSH between 0.27 - 4.2 mIU/L

      If you have any abnormal results one of our clinicians will contact you with more information. 

      How will I get my results?

      We’ll send you an email or a text to let you know when the lab has received your samples. 

      Results are usually ready in 3 working days of receipt of samples  — we’ll let you know when you can view them in your dashboard.

      Do I need to fast for weight management blood test?

      The instructions included in your test will let you know if you need to fast. However, we do recommend fasting (not eating or drinking anything except water for up to 8-12 hours) before collecting your sample.

      Your results can be affected by food and drink. Eating a high-fat meal before a lipid test could cause your triglyceride levels to look higher than they are.
