DNA Testing In London

With over half a million procedures undertaken, you're in safe hands

Do you struggle to lose weight no matter how many new-fangled diets you try? Perhaps you find it particularly hard to sleep and you have tried every trick in the book to beat your pesky insomnia? You might even have difficulty building muscle mass in spite of following your PT's advice to the letter.

Well, we're here to tell you that there may very well be a reason for this. The good news might actually be that it has absolutely nothing to do with what you're doing, and rather all to do with genetics. Now we can put that to the test!

Lesley Says

“What I love about DNA testing is that we can finally determine your perfect skincare routine - from it’s sensitivity to your need for sun protection, we can assess your skin’s needs with scientific precision.”

Dr Khan Says

“From my years of experience, I’ve found that health problems are seen only typically dealt with on a surface-level; DNA testing allows us to identify your needs on a much deeper level. Patients see life-long improvement.”

DNA Testing FAQs

The answer to some of the most common questions you may have

It's only natural to have questions if you are considering pursuing a treatment for the first time, and at Harley Street Skin, it's important to us that you feel confident and comfortable at every stage of your journey. To help you find the answers you need, here are a few of the more common quibbles that we find our clients frequently ask...

DNA Testing is an extensive genetic analysis which can identify many different things about your body's functionality. From uncovering mutations in your genes which may cause illness and disease, to assessing metabolic rate and predisposition to injury - DNA tests are the most thorough, and fail-safe route to understanding the inner workings of the unique ecosystem that is your body!

DNA Testing is not nearly as invasive as most people expect - in fact, the majority of our DNA tests simply require a small sample of the patient's saliva taken by swab. More extensive DNA tests can require more source material, in which case, patients may additionally be asked to provide a small hair and stool sample to accompany their saliva sample.

These results are then packaged and sent for laboratory testing. Following receipt of these results, patients then have the opportunity to dissect them with a Harley Street Medical Practitioner.

The amount of information that can be obtained from a DNA test is exhaustive, in fact, it spans everything from food sensitivities to sleep quality. Some things that we can test for include:


Assess sensitivities (to salt, caffeine, saturated fat, meat etc.), look at specific antioxidant requirements and response to alcohol consumption.


Identify potential issues such as predisposition to injury and recovery reports.


Scan for intel on your circadian rhythm and how you can better boost both energy levels and sleep quality based on Chronotype.


Offer insight into how we can better manage stress tolerance and anxiety levels.

Getting your DNA test results should take no longer than 10 days. Simply deposit your sample at your first appointment, and book a follow up appointment to discuss the findings with one of the Harley Street team.
