Tired All The Time · Plymouth
Tired all the time? Find out why.
43 results in one panel, covering the most common treatable causes of tiredness. Our most popular blood test. No GP referral needed.
Why test
Tiredness often has a fixable cause.
Low Iron, an underactive Thyroid, low B12, Folate or Vitamin D, low Magnesium, insulin resistance and kidney problems can all cause tiredness that has nothing to do with sleep.
This panel checks them all in one go, so nothing is missed. Many people find their energy returns once the cause is treated.

What the markers tell us.
| Test | What it covers | Why it matters |

| Full Iron Studies | Iron, Ferritin, Transferrin and Saturation | Low Iron causes tiredness even without anaemia. |
| Complete Thyroid panel | TSH, Free T4, Free T3 and both Antibodies | An underactive Thyroid causes tiredness, brain fog and weight gain. |
| Vitamin B12 and Folate | B vitamins | Low levels cause tiredness, brain fog and tingling. |
| Vitamin D | 25-OH Vitamin D | Very common in the UK, especially in winter. |
| HbA1c, Insulin and C-peptide | Blood sugar control | Insulin resistance can cause tiredness years before diabetes. |
| Magnesium and Calcium | Minerals | Low levels are linked to tiredness, cramps and poor sleep. |

Before your test

Avoid heavy exercise for 48 hours before, as it can affect the inflammation marker.
Your results
What your results mean.
Sometimes there is one clear cause, like low Ferritin or Vitamin D. Sometimes there are a few together. We look at all the results as a whole.
If everything is normal, that is useful too. It rules out the common medical causes and helps point to the next step, such as sleep, stress or mood.
Blood tests give information. They do not diagnose a condition on their own. We explain your results in the context of your symptoms, medicines and history.

About the panel
Is this what my GP would test?
Often not. Many GP checks cover a Full Blood Count and TSH. This panel adds full Iron Studies, Thyroid Antibodies, B12, Folate, Vitamin D, HbA1c, Insulin, C-peptide, Magnesium, kidney function, Calcium and CRP.
How quickly will I feel better after treatment?
It depends on the cause. Vitamin D, Magnesium and B12 often help within a couple of weeks. Iron takes longer, often 6 to 8 weeks.
What if the panel finds nothing?
That is reassuring. We can then talk about other causes, such as sleep, stress or low mood, and whether more investigation is needed.
