Frequently Asked Questions (FAQs)

Can this test tell me why I’m tired all the time?

It identifies several common biological causes of fatigue, including anaemia,
low iron, low thyroid function, and vitamin D deficiency.

Do I need to fast before this test?

No fasting is required.

Will this test diagnose thyroid disease?

It can indicate whether thyroid hormones are out of range, which may explain
symptoms but further clinical investigation may be needed.

Yes it’s ideal for anyone experiencing unexplained tiredness or low energy.

How accurate is this test?

How is Chronic Fatigue different from Chronic Fatigue Syndrome?

Chronic Fatigue is a condition of extreme tiredness caused by various factors. Whereas, Chronic Fatigue Syndrome is a disease related to the brain and central nervous system. Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) is more difficult to diagnose due to the possible complexities involved.

Can a blood test detect extreme tiredness?

Yes, a Chronic Fatigue Blood Test can help identify potential causes of extreme tiredness and low energy. It may detect underlying issues such as anaemia, vitamin deficiencies, thyroid disorders, or other imbalances contributing to exhaustion. Early detection allows for timely intervention and can support faster recovery.

What are the best supplements for tiredness?

Supplements containing vitamin B12 and folate are commonly effective in reducing symptoms of chronic fatigue. Additionally, multivitamins that include vitamin B3 (niacin), B5 (pantothenic acid), and B6 (pyridoxine) can also help support energy production and reduce tiredness.
