Long Term Health Biomarkers

Using the latest AI technology, our tests can detect possible concerns in your health before they become harder to deal with. This may be suitable for those with specific lifestyles, medical conditions, eating habits or even a family history of certain illnesses. While your long-term health may not be of any concern now, there are still reasons to evaluate and monitor the existence or progression of essential bodily functions such as cardiovascular, thyroid, nutrient and hormone health. Our test can help ease the worry and stress of the unknown to get you back to full health fast.

Ferritin (Iron Levels)

This test will check the serum ferritin levels in your blood. Iron is bound to proteins in the blood, which are referred to as ferritin and hemosiderin. However, iron is predominantly stored as ferritin, hence its use as a biomarker when checking for iron deficiency and levels. Ferritin is primarily stored in the liver. However, it can also be found in the spleen, bone marrow and muscles.


  • Ferritin
  • Iron
  • Total Iron-Binding Capacity (TIBC)
  • Transferrin Saturation

TSH (Thyroid Stimulating Hormone)

TSH (Thyroid Stimulating Hormone) or thyrotropin is secreted by thyroid gland, located in the throat, and can help identify cases of hypothyroidism and hyperthyroidism. Both the excess and under secretion of TSH can lead to weight loss, anxiety, palpitations, irregular sleep patterns and irregular menstrual cycles. Hypothyroidism is majorly associated with overlapping symptoms as menopause.

Thyroxine (T4)

Thyroxine (T4) is the hormone that has several important functions in the body, including speeding up the rate of metabolism, growth and energy levels. We test the thyroxine within the body to get an indicator of how well the thyroid is functioning. There are different treatments depending on if the thyroid is under or over the normal levels.

Full Liver Function

Worried about your liver health?

The Full Liver Function home test with Welzo is the perfect way to find out if you have any problems with your liver. This test is easy to use and can be done in the comfort of your own home. It only takes a few minutes to complete and provides accurate results that you can trust.

Once you know your results, you can take steps to improve your liver health and feel better overall. 

This test includes the following biomarkers:

1. Total Protein 

2. Albumin 

3. Globulin 

4. ALT 

5. ALP 

6. GGT 

7. Bilirubin 

8. AST

Vitamin D (Energy)

Vitamin D is a vitamin that's essential for many functions in your body, including bone and muscle health. Vitamin D can be found in food, supplements, and fortified foods. If you don't get enough vitamin D, you may develop osteoporosis or muscle weakness. An average vitamin D level is 20 to 50 ng/mL. If you have a low vitamin D level, we may recommend that you take a vitamin D supplement or eat foods fortified with vitamin D.

FT3 or free tri-iodothyronine

FT3 or free tri-iodothyronine is one of the two critical hormones produced by the thyroid gland. Its deficiency/excess is responsible for most of the thyroid related health issues because of its stronger impact even though it constitutes the lesser fraction as compared to the other hormone, FT4. Menopause blood test detects the amount of FT3 which is not attached to a protein and help to understand thyroid functioning.


Folate, folic acid or a vitamin B test checks for the serum levels of folate in the blood. Folate is essential in the healthy creation and regulation of your body's red blood cells. A typical folate rate is considered 2.7 to 17 nanograms per millilitre (ng/mL). A result lower than 2.7 ng/ml can mean you have a deficiency.

Long Term Health Biomarkers

There are many more interactions at play when evaluating your mental health. However, checking for imbalances within your body is always a good place to start. This will help to flag any abnormal ranges taken from your blood sample. 

Based on your answers, we recommend the following checks:

1. Nutrients - Our recommended test profile includes nutritional evaluation to see if any vitamins and imbalances are present in your diet.

2. Vitamin D - A recent study found that low levels of vitamin D are linked to depression and other mental health conditions. That’s why we offer a vitamin D home blood test so you can find out if you’re deficient in this essential nutrient. If you do have low levels of vitamin D, our Welzo supplement can help raise your levels and improve your mood. It’s an all-natural way to feel better without any harsh side effects.

3. Ferritin (Iron) - A recent study found that low levels of ferritin are linked with depression and anxiety. If you’re feeling down, anxious, or just not like yourself, checking your ferritin levels can help rule out any underlying issues. Knowing your ferritin levels can help you and your doctor create a treatment plan to improve your mental health. With Welzo, it’s easy to order a home blood test kit and get your results in the privacy of your own home.

4. Thyroid - Your personalised test includes the thyroid biomarker checks from Welzo. The test, which is available online, can help people determine if you have a thyroid problem.  According to the National Institutes of Health, an estimated 20 million Americans have some form of thyroid disease. Early diagnosis and treatment are important for preventing serious health problems.

Common Biomarker Issues

Based on thousands of anonymised patient data sets globally and specifically tailored to the UK, we know what the most common biomarker abnormalities are.

Therefore, we have added the biomarkers to your personalised Welzo home test.
