Private Blood Tests in Wimbledon, Common GP Questions

By Dr Umer Malik MBBS, MRCGP, MPH, GP at Mayfield Clinic Wimbledon

I am Dr Umer Malik, an experienced GP with 17 years of postgraduate clinical experience, including 9 years as a fully qualified GP, currently practising in Wimbledon. One of the most common things patients ask me about is private blood testing. In this article, I want to answer the questions I hear most often, using the same straightforward advice I give in clinic.

Private blood tests in Wimbledon, the questions patients ask most

What blood tests are available, and do you need to see a GP first?

At Mayfield Clinic Wimbledon, we offer access to over 1,500 different blood tests. These cover everything from general health screening to investigating specific symptoms or monitoring an existing condition.

In most cases, I think it is best to start with a GP consultation rather than requesting tests yourself. The right panel depends on your individual history, your symptoms, and any medications you are taking. It also means someone with the right training reviews and explains your results afterwards, rather than you being left with a list of numbers to interpret alone.

Why people commonly come in for blood tests

The reasons vary widely. Some of the most common include checking for diabetes or prediabetes, assessing cholesterol and overall heart disease risk, investigating vitamin or nutritional deficiencies such as vitamin D, B12 or iron, PSA testing for men wanting to monitor prostate health, and general health screening or monitoring an existing condition.

Another very common reason is ongoing tiredness or fatigue. This can have a wide range of underlying causes, from thyroid function to iron levels to blood sugar, and blood tests can help narrow that down. Whatever the reason, I would always guide you towards the right tests for your specific situation.

What happens on the day, and do you need to prepare?

Most blood tests are taken from a vein in your arm, similar to what you would expect from any GP or hospital setting, and the sample usually takes only a few minutes.

Some tests, particularly those looking at cholesterol or blood sugar, may require fasting beforehand. That usually means no food for around 8 to 12 hours, though water is fine. I would let you know in advance if any preparation is needed for the specific tests you are having, so you are not caught out on the day.

How long results take, what they mean, and what happens if something is abnormal

Turnaround time depends on the specific tests requested. Many results are available the same day, while some more specialised tests can take longer.

What matters just as much as speed is interpretation. Results are reviewed by a GP so you understand what they actually mean for you, rather than simply receiving raw figures. If anything needs following up, whether that is a repeat test, a referral, or starting treatment, this can usually be arranged as part of the same consultation pathway.

If something comes back abnormal, it does not necessarily mean something serious. Many things can affect a single reading, but it does need proper assessment. I can explain what the result means, arrange any further investigation needed, or refer you on if appropriate, all as part of the same pathway rather than leaving you to interpret it alone or start again with someone new.

An abnormal result does not automatically mean something serious, but it does deserve proper assessment and explanation.

Costs vary depending on which tests are needed, so it is best to check current pricing on our website or discuss this with your GP before booking.
