Many people put off having a blood test until symptoms become more serious, but regular checks can catch early signs of imbalance or illness. If you’ve noticed any of the following, it might be worth speaking to a clinician about having a blood test.

1. You’re feeling unusually tired

Persistent fatigue could be linked to iron deficiency, low B12, or thyroid issues — all of which can be identified through a simple blood test.

2. Your skin or nails are changing

Pale skin, brittle nails or hair thinning may be signs of nutritional deficiencies such as low iron, zinc, or vitamin D.

3. You’re experiencing mood changes

Hormonal imbalances and low vitamin B12 or D levels can affect your mood and mental clarity. A blood test can help identify possible causes.

4. You have a long-term condition

If you have diabetes, high cholesterol, or a thyroid condition, regular blood tests help track how well your treatment is working and if any adjustments are needed.

5. You haven’t had one in a while

Even if you feel well, a general health check can give you peace of mind. Many common conditions show no symptoms in the early stages.
