PGT-A Testing London – Embryo Genetic Screening for IVF
Improve IVF success rates with advanced embryo genetic testing. Detect chromosomal abnormalities before implantation with private PGT-A testing in Central London.
PGT-A testing (Preimplantation Genetic Testing for Aneuploidy) is an advanced technique used during IVF to assess the chromosomal health of embryos before implantation.
At Marylebone Diagnostic Centre, we provide private PGT-A testing in London, helping fertility patients and clinics select the healthiest embryos and improve the chances of a successful pregnancy.
PGT-A is especially valuable for those experiencing recurrent IVF failure, miscarriage, or advanced maternal age.
WHAT IS PGT-A TESTING?
PGT-A analyses embryos for chromosomal abnormalities, also known as aneuploidy. Embryos with abnormal chromosome numbers often face critical challenges.
Risks of Abnormal Chromosome Numbers:
PGT-A allows clinicians to select embryos with the correct number of chromosomes, improving outcomes.
WHO SHOULD CONSIDER PGT-A?
PGT-A testing is recommended for:
- Women over 35
- Recurrent miscarriage
- Multiple failed IVF cycles
- Known chromosomal abnormalities
- Couples undergoing advanced fertility treatment
Unsure where to start?
Consider starting with a Genetic Compatibility Test (GCT) for carrier screening to understand shared inherited risks.
Explore GCT Options →TYPES OF PGT-A TESTING
Standard PGT-A (NGS-Based)
- Embryo biopsy at blastocyst stage
- High accuracy chromosomal screening
Non-Invasive PGT-A (niPGT-A)
- Analyses DNA from embryo culture media
- No direct embryo biopsy
- Emerging alternative with reduced invasiveness
HOW PGT-A WORKS
Step 1: IVF Cycle
Eggs are fertilised in the lab
Step 2: Embryo Development
Embryos grow to blastocyst stage
Step 3: Embryo Biopsy
A few cells are carefully removed
Step 4: Genetic Analysis
DNA is analysed using advanced sequencing
Step 5: Embryo Selection
Only chromosomally normal embryos are selected
PGT-A VS OTHER GENETIC TESTS
| Test | Purpose |
|---|---|
| GCT | Detect inherited carrier risks before pregnancy |
| PGT-A | Screen embryos for chromosomal abnormalities |
| PGT-M | Detect specific inherited diseases in embryos |
| Karyotype | Analyse parental chromosomes |
WHAT HAPPENS AFTER RESULTS?
Your results will show:
- Chromosomally normal embryos
- Abnormal embryos
- Mosaic embryos (in some cases)
Next Steps Based on Results:
- Healthy embryos are prioritised for transfer
- Genetic counselling may be recommended
- Further testing may be advised
