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 helps to understand thyroid functioning.

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 the 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.

Energy Level Test

We are able to test your general energy levels through your biomarkers by evaluating common causes of fatigue, tiredness and lack of energy. Based on your answers, we have identified that the following biomarkers might give some insight into your current energy levels and help to flag any outstanding issues. 

1. Our analysis has shown that an Iron (Ferritin) Test will be beneficial. If your levels are below average (which is quite common), then you will be subject to fatigue. This can be mitigated through changes in diet and supplementation. 

2. Secondly, based on your answers, checking your thyroid function can rule out any thyroid issues. Problems with T4 and T3 production can result in very poor energy levels. 

3. We recommend you evaluate our vitamin D levels. One in six adults in the UK currently has a vitamin D deficiency which can greatly impact your general energy and well-being.  

General Health

Based on your individual answers, we recommend a general health check is suited to you. 

To help rule out any underlying issues, we recommend checking your baseline general health. We have integrated multiple general health checks into your personalised Welzo home test. These are covered by checking your liver function, iron levels, thyroid function, energy levels and much more. 

Welzo offers a personalised home blood test that can help you understand your general health. We'll provide you with a detailed report on your blood markers, including cholesterol levels, liver function and more.

With this information, you'll be able to take control of your health and make informed decisions about the best way to improve your well-being. 

Mental 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. Cortisol Levels - Cortisol is a hormone that helps the body deal with stress. When cortisol levels are too high, it can cause health problems like weight gain, high blood pressure, and diabetes. That’s why it’s important to test your cortisol levels regularly and keep them in check. Welzo offers an easy-to-use home cortisol blood test that you can do yourself in the comfort of your own home. Just prick your finger and collect a drop of blood, then put the sample into the included tube. Send it in for analysis and receive your results in just a few days. Keep track of your cortisol levels over time to see if they’re changing – and take action if they are.

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.

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. 

We have found that many other patients in the UK have experienced issues with these specific biomarkers. Therefore we highly recommend that these are tested for in your personalised test.
