The Benefits of Having a Blood Test

Last updated: 14 January 2026

A blood test is one of the simplest and most effective ways to understand your health. It measures key markers in your body that can reveal early signs of disease, monitor existing conditions, and give you a clearer picture of your overall wellbeing.

At Bluecrest Wellness, we make private blood testing quick, accurate and stress-free - helping you take control of your health with professional results you can trust.

Why blood tests matter

Blood tests provide valuable information about how your body is functioning. They can:

  • Detect early signs of illness before symptoms appear

  • Monitor chronic conditions such as diabetes or high cholesterol

  • Assess organ health, including liver, kidney, and thyroid function

  • Measure vitamin and mineral levels

  • Track changes in your health over time

Because many health conditions develop silently, regular blood testing can make all the difference in early diagnosis and prevention.

What a blood test can reveal

Your blood contains a wide range of markers that tell a detailed story about your health. Depending on the test, your results may provide insights into:

  • Heart health – cholesterol and lipid levels

  • Diabetes risk – glucose and HbA1c readings

  • Nutrient balance – vitamin D, B12, folate, and iron stores

  • Hormone levels – thyroid and reproductive hormones

  • Inflammation and immunity – C-reactive protein (CRP) and white blood cell count

Each result helps you and your healthcare provider make informed decisions about your wellbeing.

Convenient, professional testing

At Bluecrest Wellness, your blood test is performed by a trained health assessment specialist at one of over 350 UK and Ireland venues, ensuring high-quality, professional care.

You can choose to have a blood test as part of a full health assessment or add an individual test to any package.

Your results explained clearly

Your personalised Results Report is easy to understand and free of medical jargon. Each result includes:

  • A clear reading for every test performed

  • A color-coded flag system - green (normal), amber (slightly outside), or red (outside normal range)

  • Guidance on what your results mean and when to follow up with your GP

You can access your report 24/7 through your secure My Wellness dashboard, and most results are ready in just a few days.

Private health checks for complete peace of mind

Our full body health assessments are designed for busy people who want to stay proactive about their health. With no long waiting times or invasive procedures, they provide an efficient way to monitor your wellbeing.

Any individual blood test can be added to your chosen health package - simply book your assessment and contact us before your appointment to include additional tests.

FAQs

How often should I have a blood test?

For most adults, a yearly blood test is a good way to monitor key health markers. However, if you have a medical condition or specific risk factors, more frequent testing may be recommended.

Some tests, like glucose or lipid profiles, may require fasting for 8–10 hours. You’ll receive clear instructions before your appointment.

How long do results take?

Most Bluecrest Wellness blood test results are available within a few days and accessible through your online dashboard.

Can I add a blood test to an existing package?

Yes. You can add any individual test to your existing health assessment - just contact us before your appointment.
