Blood tests

Understanding comprehensive private blood testing in Marylebone

Fast access. Same named GP. Clear answers. If you live or work in Marylebone and want reliable, detailed blood testing without long waits, Mayfield Clinic offers tailored private blood tests with rapid turnaround and expert interpretation.

Why choose private blood testing?

Private blood testing gives you control: choose the tests you need when you need them. At our Mayfield Clinic service serving Marylebone patients (appointments taken at our nearby St John's Wood practice), we can arrange over 1,500 tests — from a full blood panel to specialised hormone and autoimmune screens. Results are typically returned in days rather than weeks, and your GP will explain each finding and advise next steps.

What we test for

Our comprehensive blood testing includes routine screens like FBC (full blood count), liver and kidney panels, lipid profiles and glucose, plus advanced investigations such as thyroid function, vitamin and mineral levels, sex hormones, inflammatory markers and disease-specific assays. If you need a complete blood screening or detailed blood work in Marylebone, we personalise the panel to your symptoms, history and goals.

How the process works

Book online via the Book now button. Members can book by phone or WhatsApp. Your appointment is with a named GP from Mayfield Clinic who will review your symptoms and request the appropriate tests. Bloods are taken at St John's Wood for Marylebone patients; samples are processed by accredited labs and results returned quickly. Your GP then reviews the results and provides a clear, actionable plan.

Speed and continuity: the clinical difference

Fast results matter. If a thyroid abnormality or vitamin deficiency is detected, earlier treatment often improves outcomes. Continuity matters too — seeing the same GP builds context. At Mayfield Clinic we prioritise rapid access to the same named doctor so your blood test results are interpreted by someone who knows your history and can make safe, personalised recommendations.

Interpreting results: what to expect

Your GP will explain numeric values and what they mean for your health. Expect explanations on reference ranges, possible causes of abnormalities and recommended actions: further tests, lifestyle changes, medication or referral. For example, a mildly low ferritin (iron stores) may prompt dietary advice and a short course of supplementation; a raised inflammatory marker might lead to targeted imaging or specialist referral.

Specialist testing options

Beyond standard panels we offer advanced blood testing private patients value: dynamic hormone profiles, full autoimmune screens, vitamin D and B12 subtypes, genetic-related assays, allergy-related blood tests and infection serology. These can be particularly useful for unexplained fatigue, fertility assessment, hair loss or chronic digestive problems.

Practical details for Marylebone patients

Although marketed to Marylebone residents, our blood draws and consultations are delivered from our St John's Wood clinic. Visit our Marylebone information page at Mayfield Clinic Marylebone to learn more, then book a slot — your appointment will take place at St John's Wood. Travel between Marylebone and St John's Wood is short, and patients often combine visits with local errands or work commitments.

Costs and turnaround

Private test costs vary by complexity. We provide transparent pricing at booking. Standard panels typically return within 24–72 hours; specialised assays may take longer. Your GP will set expectations when ordering tests.

Actionable care after testing

Receiving numbers is not enough. We focus on next steps: medication changes, targeted supplements, lifestyle programmes or onward referral. If repeat monitoring is needed, your named GP arranges follow-up testing at appropriate intervals so results can be tracked over time.

“The aim is clear: fast, accurate blood testing with a doctor who understands your full health story.”
