Genetic tests, explained.
We're not a typical direct-to-consumer test shop. Genetics is nuanced - most tests include a consultation with a clinician (a genetic counsellor, midwife or GP, depending on the test) before you test, so you understand what each test measures, what it can't, and which one actually fits your situation. Each product page says exactly what is included. We're here to explain, not just to sell.

Pre-conception, pregnancy-planning and post-birth testing - carrier screening for couples, karyotype chromosome analysis, newborn genetic screening, and male fertility testing.
Carrier Screening
Pre-conception screen of 1,008 genes for inherited recessive disease - for couples planning a pregnancy.
Carrier Screening + Karyotype
The complete pre-conception genetic work-up - our 1,008-gene carrier panel bundled with chromosome-level karyotype analysis. One counselling session, one blood draw, one integrated report.
Karyotype Chromosome Analysis
Chromosome-level analysis of all 46 chromosomes - detects numerical changes (aneuploidies) and large structural rearrangements. Useful for couples investigating recurrent miscarriage or fertility issues.
Newborn Genetic Screening
A simple oral-swab screening test of 258 genes linked to inherited conditions that can affect babies, including metabolic disorders, immune deficiencies and some causes of hearing loss, some of which can be treated or managed more effectively when they are found early. It is an additional private test: it does not replace the NHS newborn blood spot test, and it is a screening test, not a diagnosis.
SMA Newborn Testing
An at-home cheek-swab DNA test that looks for spinal muscular atrophy (SMA), a rare genetic condition that can cause muscle weakness that gets worse over time, by analysing the SMN1 and SMN2 genes. It is a private screening test, not a diagnosis, and it does not replace the NHS newborn blood spot test. A positive result needs confirming with diagnostic testing arranged through a specialist paediatric service.
CGT - Igenomix Carrier Genetic Test
Whole-exome carrier genetic test from Igenomix - reports 1,993 (male) / 2,057 (female) genes covering >2,200 inherited recessive conditions. 30-minute genetic counselling included. Blood collection is not included: +£40 at a partner collection point, +£65 for a home-nurse visit.
Sperm Analysis in London
Comprehensive semen analysis at The Doctors Laboratory on Wimpole Street, reported against WHO 2021 reference values. Includes an online consultation with our male-health GP. Results in 2-3 working days.

Hereditary Cancer Screening 8
Genetic-risk panels for inherited cancer predisposition - breast, prostate, ovarian, colorectal, pancreatic, plus a comprehensive 50-gene screen.
BRCA Testing
10-gene panel covering BRCA1, BRCA2 and eight other genes linked to hereditary breast, ovarian, prostate and related cancer predisposition.
Cancer Risk Screening
Comprehensive 50-gene hereditary cancer-risk panel.

13-gene panel focused on hereditary breast cancer predisposition.
Prostate Cancer Risk Screening
13-gene panel focused on hereditary prostate cancer predisposition.

12-gene panel focused on hereditary ovarian cancer predisposition.
Colorectal Cancer Risk Screening
14-gene panel focused on hereditary colorectal cancer predisposition.

10-gene panel focused on hereditary pancreatic cancer predisposition.
Combined Cancer + Carrier Screening
Hereditary-cancer 50-gene panel bundled with our 1,008-gene carrier-screening panel - one counselling session, one report, one price. Best value when you want both pre-conception risk insights and your own cancer predisposition assessed together.
Disease Panels 5
Targeted single-condition genetic panels - for confirming a clinical diagnosis, family-planning, or pre-symptomatic risk assessment when there's a known family history.
Polygenic Risk Score Test
A polygenic risk score (PRS) test that reads large numbers of common DNA variants to estimate your inherited risk across 20+ conditions - common cancers, heart disease and stroke, cholesterol and lipids, type 2 diabetes, Alzheimer's and more. Ancestry-specific analysis by Allelica, from one home saliva sample. It estimates inherited risk only - not a diagnosis, and not a replacement for NHS screening - and predictive performance varies by condition and ancestry.
Genomics Health Insights
Health Insights, from the Oxford genetics company Genomics, combines a polygenic risk score from a home saliva sample with your ethnicity for breast or prostate cancer - and, for cardiovascular disease and type 2 diabetes, with your health check and the QRISK®3 and QDiabetes®-2018 calculators trusted by the NHS - to give a personal risk estimate for each condition. GP consultations before and after, and a blood test, are included. For adults aged 25 to 69. It estimates genetic risk - it is not a diagnosis.
Medication Check + Genetic Disease Risk
Our Pharmacogenomic Medication Check and Polygenic Risk Score tests bundled into one home saliva kit - how your body processes common medicines, plus your inherited risk across more than 20 conditions. £419 vs £509 ordered separately.
Pharmacogenomic Test
A DNA medication-compatibility test (PGx) that screens 112+ medications across 14 therapy areas - find out which drugs are likely to work for you, which might cause side effects, and which need a different dose.
Polycystic Kidney Disease (PKD) Panel
Genetic screening for autosomal-dominant and recessive polycystic kidney disease. Identifies pathogenic variants in PKD1, PKD2 and PKHD1 - useful for confirming a clinical diagnosis, family planning, or pre-symptomatic risk assessment when there's a family history.
