What we measure

This test looks for signs of health issues that commonly cause fatigue, including thyroid problems and a deficiency in iron or vitamin D. If you've been feeling tired a lot lately, this test can help you figure out whether there may be an underlying health reason.

This test can help indicate health issues that are causing symptoms of fatigue.

Feeling tired from time-to-time is perfectly normal—and unavoidable for most of us. But when you’ve been feeling constantly tired for more than four weeks, something else might be going on.

Fatigue is a symptom of many different diseases, but there are some conditions it’s more strongly associated with. Thyroid disease is one example: the thyroid regulates how the body uses energy, so when it’s not working as it should this tends to make us feel lethargic and tired.

Another common cause of fatigue is an iron deficiency. Iron plays a crucial role in transporting oxygen around the body, which your muscles use as energy. Without enough iron, your body doesn’t get the energy it needs to function—and you feel tired as a result.

This test can help you to figure out whether your fatigue is being caused by a health problem. It looks for signs of disease and nutritional deficiencies, and can be a useful first step in finding out what’s happening inside your body.

Your results:
what to expect

Your results will tell you how much of each substance measured in present in your blood, and whether this falls within a normal range.

If any of your readings are abnormal (i.e., outside of the normal range), it can be a sign of a health problem that commonly causes tiredness.

Think of your results as a general overview of what’s going on inside your body: they can tell you what looks to be in order and where there may be an issue. You and your doctor can use these insights to help decide what you should do next—which may be to make certain lifestyle changes, for example, or to investigate further.

Do I need to fast for this test?

Nope, you don’t need to abstain from food or drink ahead of this test.

How should I prepare for this test?

Because this test measures thyroid function, you should avoid taking the vitamin B supplement biotin for at least 48 hours before the test. Biotin can cause false results in thyroid blood tests.

If my results are abnormal, what should I do next?

If your results show that you’ve got abnormal levels of one or more of the substances measured, this can indicate that you’ve got a health problem. But this isn’t a diagnosis.

Only a doctor can confirm whether you have a disease or nutritional deficiency. You should speak with them about your results—they’ll be able to explain what your readings mean for your health, decide whether it’s best to run further tests, and advise on any treatment options.

What are the early warning signs of thyroid problems?

Symptoms may differ depending on whether your thyroid is producing too many hormones (hyperthyroidism) or too few (hypothyroidism).

Some common signs of hyperthyroidism include:

  • Feeling tired all the time
  • Anxiety, irritability, and nervousness
  • Feeling hyperactive, like you can’t stay still and have a lot of nervous energy
  • Mood swings
  • Trouble sleeping
  • Muscle weakness

Some symptoms of hypothyroidism are:

  • Tiredness
  • Weight gain
  • Constipation
  • Depression
  • Muscle aches and weakness
  • Being sensitive to the cold
Is this test accurate?

Yes, this test is accurate in measuring the substances in your blood that may be related to fatigue. Your results are not a diagnosis in themselves, though—only a doctor can diagnose you with disease.

All of our tests follow the highest quality standards for health services: we’re CQC regulated, which is a quality marker for health services you can trust, UKAS accredited, and have our tests validated by registered doctors and clinical scientists.

How long does the test take?

The test won’t take longer than a few minutes.

For a phlebotomy, you’ll simply need to go to your local pharmacy and have them draw your blood.

Can I take this test during my period?

Yes, absolutely. You can take this test at any point during your menstrual cycle.
