Why would I need a blood test?

Blood tests are one of the most powerful tools for understanding your health. They help detect early signs of illness, monitor ongoing conditions, and provide a clear picture of how your body is functioning. You might need a blood test to:

  • Identify underlying issues like anaemia, thyroid problems, or hormonal imbalances that could be affecting your energy, mood, or weight.
  • Assess risk factors for serious conditions such as heart disease, diabetes, or liver and kidney disorders—even if you’re not showing symptoms.
  • Track vital nutrients like iron, vitamin D, B12, and folate, which are essential for immunity, bone strength, and overall wellbeing.
  • Understand changes in your body due to age, lifestyle, stress, or menstruation.

  • Take control of your health, with clear, science-backed insights you can act on whether for prevention or peace of mind.

Paying for your blood test

All blood test services offered by Vitalscan are self-pay only. We do not accept private medical insurance for these tests, and they cannot be claimed through your insurer. Payment must be made in full at the time of booking.

Tired all the time? Symptoms vs possible causes

Understanding your tiredness symptoms can help identify which blood tests may be appropriate.

Ongoing fatigue and low energy

  • Feeling tired even after a full night’s sleep

  • Struggling to get through the day

  • Low motivation or reduced stamina

  • Brain fog and poor concentration

  • Feeling weak, run down, or drained

  • Low mood or irritability

  • Muscle aches or heavy limbs

  • Needing naps or relying on caffeine

Blood tests for ongoing tiredness

Blood tests for ongoing tiredness can help identify whether your fatigue may be linked to low iron stores, vitamin deficiencies, thyroid imbalance, inflammation, or other common health markers.

Results may highlight issues such as low ferritin, iron deficiency, low vitamin D, abnormal thyroid hormone levels, raised inflammation markers, or changes in red blood cell health.

Signs your tiredness may be health-related

  • Tiredness that does not improve with rest

  • Feeling cold more often than usual

  • Shortness of breath during normal activity

  • Dizziness or feeling light-headed

  • Headaches or heart palpitations

  • Hair thinning or dry skin

  • Unexplained weight changes

  • Low mood, anxiety, or poor sleep

  • Frequent infections or slow recovery

Blood tests for possible causes of fatigue

A tiredness blood test can check key markers linked to energy, metabolism, immunity, and general wellbeing.

This test focuses on key markers linked to fatigue, including thyroid function, vitamin D, iron levels, ferritin, and inflammation. These biomarkers help identify some of the most common causes of ongoing tiredness.

Both symptom patterns can be investigated through a simple blood test panel. The results may help explain why you feel tired all the time and guide the most appropriate next steps.

These symptoms can be investigated through a targeted blood test panel measuring key fatigue-related biomarkers. The pattern of results helps identify potential underlying causes of your tiredness.

Understanding your blood test results

Your tiredness blood test results show key biomarkers linked to energy, fatigue, and general wellbeing.

  • Iron and ferritin levels: Low iron or ferritin may suggest reduced iron stores, which can contribute to tiredness, weakness, dizziness, or feeling run down.

  • Vitamin D levels: Low vitamin D can be associated with fatigue, muscle aches, low mood, and reduced general wellbeing.

  • Thyroid markers: TSH, FT4, and FT3 help assess whether your thyroid may be contributing to tiredness, changes in weight, mood changes, or feeling unusually cold.

  • Inflammation marker: HS-CRP can indicate raised inflammation in the body, which may sometimes be linked to ongoing fatigue or poor recovery.

  • Iron transport markers: TIBC and transferrin saturation help show how well your body is transporting and using iron.

All results should be reviewed in context with your symptoms, medical history, and individual circumstances. Your report can be shared with your GP or clinician to support further advice, treatment, or next steps.

No. You can book a private blood test at Vital Scan without a GP referral.

How quickly will I receive my blood test results?2026-01-14T12:21:14+00:00

Most results are returned within a few working days, depending on the test.

Are private blood tests accurate?2026-01-14T12:21:00+00:00

Can I share my results with my GP?2026-01-14T12:22:23+00:00

Yes. Your results can be shared with your GP or healthcare provider if required.

What’s the difference between a full blood test and individual tests?2026-01-19T12:56:20+00:00

A full blood test assesses multiple body systems in one panel, including liver function, kidney health, cholesterol, and blood counts. Individual tests focus on specific concerns like thyroid function or vitamin levels. Full tests are better for general health checks, while targeted tests suit monitoring known conditions.

Can I get same-day blood test appointments?2026-01-19T12:56:51+00:00

Yes. Same-day appointments are often available depending on demand. Contact us on 01908 755556 to check availability.

What conditions can blood tests detect?2026-01-19T12:57:17+00:00

Blood tests can identify markers indicating liver disease, kidney problems, diabetes, thyroid disorders, anaemia, high cholesterol, vitamin deficiencies, and inflammation. Abnormal results may require follow-up testing or medical review.

How long do blood test results take?2026-04-30T20:52:32+00:00

Blood test results are usually available within a few working days, depending on the type of test and laboratory processing times.

For VitalScan blood tests, results are provided in a clear report with explanations, and you can share them with your GP or specialist if further advice is needed.

Can cancer be identified with a blood test?2026-04-30T20:52:49+00:00

Some blood tests can show signs that may need further investigation, such as inflammation, anaemia, abnormal liver markers, or specific tumour markers. However, a standard blood test cannot reliably confirm or rule out cancer on its own.

Cancer diagnosis usually requires further assessment, which may include a GP or specialist review, imaging scans, biopsies, or more specific tests.

For a tiredness blood test, the results may help identify common causes of fatigue such as low iron, low vitamin D, thyroid imbalance, or inflammation, but it is not designed as a cancer screening test.
