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:

Often fail to implant
May result in miscarriage
Can lead to genetic conditions (e.g. Down syndrome)

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.

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

1
Step 1: IVF Cycle

Eggs are fertilised in the lab

2
Step 2: Embryo Development

Embryos grow to blastocyst stage

3
Step 3: Embryo Biopsy

A few cells are carefully removed

4
Step 4: Genetic Analysis

DNA is analysed using advanced sequencing

5
Step 5: Embryo Selection

Only chromosomally normal embryos are selected

FAQs

PGT-A is a genetic test used during IVF to check embryos for chromosomal abnormalities before implantation.

Yes. It helps select healthy embryos, increasing the chances of implantation and reducing miscarriage risk.

Embryo biopsy is a well-established technique and is considered safe when performed by experienced embryologists.

PGT-A screens for chromosomal abnormalities, while PGT-M detects specific inherited genetic diseases.

Results are typically available within 14 to 19 days.
