Another 23andMe?

At Jeen, we focus on health, not hair colour. Our genetic testing uses 50x sequencing depth (NGS) for greater accuracy and confidence in detecting inherited conditions.

How DNA Sequencing Works - illustration

How DNA Sequencing Works

DNA is broken into small fragments, sequenced, and computationally assemble into the full genome.

What is Sequencing Depth? - illustration

What is Sequencing Depth?

Sequencing depth is how many times your DNA is read. Higher depth = more accurate results, lower depth = risk of missed mutations.

Genome Size Matters! - illustration

Genome Size Matters!

Larger genomes (like humans) need more sequencing reads. That’s why high-depth testing matters-it ensures nothing is missed.

Why Jeen?

Not all genetic tests are created equal. At Jeen, we use 50x sequencing coverage, which means each section of your DNA is read around 50 times. Here’s why it makes a difference:

  • Bigger genome → more data needed
  • Higher depth → better accuracy
  • Balance cost vs. detail!

What Now?

Have questions? We’re here to help. Genetic testing can feel overwhelming, but it doesn’t have to be. Our genetic counsellors are here to walk you through your options, explain the science in plain English, and help you decide if testing is right for you.

What do we test for?

Know your genes, protect your future. Over 5,000 diseases are linked to genetic mutations. Early insights through genetic testing can help with prevention, early detection and personalised healthcare decisions.

NIPT Testing Options

NIPT gives you a safe and early look at your baby's health – explore the conditions we can screen for during pregnancy.

Frequently Asked Questions

What is genetic testing?

Genetic testing looks at your DNA to find changes or variants in your genes. These changes can tell us if you’re at risk for certain inherited conditions, like hereditary cancers or if you’re a carrier for a genetic condition.

What can genetic testing tell me?

It can reveal if you have a higher genetic risk for certain cancers (like breast, ovarian or bowel), if you’re a carrier for inherited conditions, or if you have a genetic condition that could impact your health or your family’s.

Will the results tell me if I’ll definitely get a disease?

No - genetic testing shows your risk, not a guarantee. Some people with a genetic variant never develop the condition, while others without a variant might still be affected due to lifestyle or environmental factors.

How does it work?

It’s simple - you speak with one of our expert Genetic Counsellors, receive a home kit in the post, collect a cheek swab, and send it back. Your DNA is analysed in a UK or US lab, and results are ready in under 4 weeks.

Is my data safe and private?

Yes. At Jeen Health, your data is encrypted and stored securely on our GDPR compliant servers, as well as with our vetted laboratories. Your results are only shared with you and your dedicated Genetic Counsellor, never with insurers or third parties.

Is genetic testing only for people with a family history of disease?

Not at all. While a strong family history increases your risk, many people with genetic conditions have no known family history. Testing helps you uncover hidden risks you wouldn’t otherwise know about.
