Genetic tests, explained.
We're not a typical direct-to-consumer test shop. Genetics is nuanced - every order includes a free clinician consultation before your kit ships, so you understand what each test measures, what it can't, and which one actually fits your situation. 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 screen of your newborn for inherited conditions where early intervention changes outcomes - including treatable metabolic disorders, hearing impairment risk, and immune deficiencies.
SMA Newborn Testing
An at-home oral-swab DNA test that screens your baby for Spinal Muscular Atrophy (SMA) - the leading genetic cause of infant mortality in the UK. SMA is not on the NHS heel-prick panel; early detection lets your paediatric team start MHRA-approved treatments before motor-neurone loss becomes irreversible.
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.

Non-invasive prenatal screen from 10 weeks. 3 conditions, 2–4 day turnaround.
VeriSeq v2 NIPT
Non-invasive prenatal screen from 10 weeks, analysed on Illumina's VeriSeq v2 platform at TDL Genetics in the UK. Screens the 3 most common chromosomal conditions plus optional fetal sex, with a 3-4 day turnaround.
Panorama NIPT

KNOVA
One of our most advanced non-invasive prenatal tests, screening for a broader range of chromosomal, genetic and rare conditions in your baby - including monogenic disorders most NIPTs miss.
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 the most actionable BRCA-pathway genes - hereditary breast, ovarian, prostate and related cancer predisposition.
Cancer Risk Screening
Comprehensive 50-gene hereditary cancer-risk panel.
Breast Cancer Risk Screening
13-gene panel focused on hereditary breast cancer predisposition.
Prostate Cancer Risk Screening
13-gene panel focused on hereditary prostate cancer predisposition.
Ovarian Cancer Risk Screening
12-gene panel focused on hereditary ovarian cancer predisposition.
Colorectal Cancer Risk Screening
14-gene panel focused on hereditary colorectal cancer predisposition.
Pancreatic Cancer Risk Screening
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 4
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.
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 for five major 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.
