Introduction
PGT — preimplantation genetic testing — is a family of three different tests that get confused constantly. They have different purposes, different costs, and very different patients they make sense for. This guide breaks down PGT-A, PGT-M, and PGT-SR in plain English, with real 2026 pricing and the medical scenarios where each one is appropriate.
The three flavors of PGT
PGT-A (Aneuploidy)
Screens embryos for the right number of chromosomes (46, with 23 from each parent). Aneuploidy — having an extra or missing chromosome — is the leading cause of IVF failure and miscarriage. PGT-A picks the embryos most likely to result in a healthy pregnancy.
Used by: ~45 percent of US IVF cycles, ~20 percent of Canadian cycles
PGT-M (Monogenic / Single Gene)
Tests for a specific inherited genetic disease when one or both parents carry a known mutation. Examples: cystic fibrosis, Huntington's disease, sickle cell, BRCA1/2, Tay-Sachs, fragile X.
Used by: Couples with known carrier status or family history
PGT-SR (Structural Rearrangement)
Tests for chromosomal translocations or inversions when a parent has a balanced rearrangement (their cells have the right amount of DNA, but it's structurally rearranged). These parents have high miscarriage rates because they produce many unbalanced embryos.
Used by: Couples where karyotype testing has identified a translocation
How PGT actually works
All three tests use the same physical process:
- Embryos grow to the blastocyst stage (day 5–6 after fertilization)
- The embryologist biopsies 5–10 cells from the trophectoderm (the part that becomes placenta, not baby)
- Embryos are vitrified (frozen) while biopsies are shipped to a genetics lab
- Lab reports back in 7–14 business days
- Only chromosomally normal (or genetically clear) embryos are transferred in a subsequent FET
The biopsy itself is the same; the lab analysis is what differs in cost and complexity.
2026 costs (USD / CAD)
PGT-A
- US: $3,500–$7,500 for up to ~8 embryos
- Canada: CAD $3,500–$6,000 for up to ~8 embryos
- Per-embryo charge if more than 8: $200–$500 each
- Often not covered by insurance even in mandate states; sometimes covered by Progyny
PGT-M
- US: $5,000–$12,000 (one-time custom probe development $3,000–$5,000 + per-embryo testing)
- Canada: CAD $5,500–$11,000
- Probe development is one-time per family; subsequent cycles use the existing probe
- Sometimes covered by insurance when genetic indication is documented (e.g., BRCA carrier, CF parent)
PGT-SR
- US: $4,500–$8,500
- Canada: CAD $4,500–$7,500
- Cost slightly higher than PGT-A due to translocation-specific analysis
- Often covered when karyotype-documented translocation
Combined PGT-A + PGT-M
Possible and increasingly common (e.g., BRCA carrier who also wants aneuploidy screening). Typically $7,500–$15,000 combined.
Indications for each test
When PGT-A is reasonable
- Advanced maternal age (typically ≥37): aneuploidy rates rise sharply with age, jumping from ~25 percent at 35 to ~70 percent at 42
- Recurrent pregnancy loss (2+ miscarriages)
- Recurrent implantation failure (3+ failed transfers of good-quality embryos)
- Severe male factor with high sperm DNA fragmentation
- Sex selection for family balancing (legal/ethical varies by jurisdiction — Canada bans non-medical sex selection)
When PGT-A is controversial
- Patients under 35 with no history of loss or failure: 2021 STAR trial showed no overall live birth benefit, and embryos may be falsely labeled "abnormal" (mosaicism)
- Patients with very few embryos (1–2): testing risks losing the only viable embryo to no-result or biopsy damage
See our PGT-A worth it guide for the deeper evidence review.
When PGT-M is indicated
- One or both parents are known carriers of a recessive disorder (CF, SMA, sickle cell, Tay-Sachs)
- One parent has an autosomal dominant condition (Huntington's, BRCA1/2, MEN1)
- Family history of X-linked disorders (Fragile X, Duchenne)
- Prior affected child
- Save-a-sibling cases: HLA matching to create stem cell donor for existing sick sibling (legal in US, Canada, UK; restricted elsewhere)
When PGT-SR is indicated
- One parent has a balanced reciprocal or Robertsonian translocation
- One parent has a pericentric or paracentric inversion
- Recurrent pregnancy loss with documented translocation
PGT-SR couples often have >50 percent unbalanced embryos per cycle, so the test dramatically improves per-transfer success rates.
Hidden costs around PGT
- Genetic counseling: $200–$600 per session, often required before PGT-M
- Karyotype testing (for PGT-SR diagnosis): $300–$800 per partner
- Carrier screening (for PGT-M decisions): $300–$1,500 per partner
- Shipping of biopsy samples to the genetics lab: $50–$200
- Mosaic embryo consultations: increasingly common, may add $200–$500 of counseling
- Re-biopsy fees for inconclusive results: $500–$2,000
- Frozen embryo transfer required after biopsy: $2,500–$6,500
Insurance and coverage
US
PGT-A coverage is patchy even in mandate states. PGT-M coverage is much more common with documented genetic indication — most insurers will cover it when a clinical geneticist confirms the mutation. Progyny covers all three; Carrot variable; most flat-dollar plans don't.
Canada
Provincial funding programs (Ontario OFP, Quebec RAMQ) do not cover PGT — it is patient-pay. The Medical Expense Tax Credit applies. Manitoba and Saskatchewan refundable credits stack.
The success rate impact
For appropriate patients:
- PGT-A: typically increases per-transfer live birth rate by 10–25 percentage points by avoiding transfer of aneuploid embryos. Does NOT increase per-cycle birth rate as much, because aneuploid embryos would have failed anyway.
- PGT-M: prevents transfer of affected embryos. Per-transfer success similar to non-PGT cycles.
- PGT-SR: dramatically improves outcomes for translocation carriers, often doubling per-transfer success rate.
A decision framework
- Under 35, no losses, no genetic history: usually skip PGT-A; no indication for PGT-M/SR
- 37+ or 2+ miscarriages: discuss PGT-A seriously
- Known mutation carrier: PGT-M is the standard of care
- Known translocation: PGT-SR is the standard of care
- Very few embryos (1–2): PGT-A risk/benefit tilts against testing
Using the Navigator
The Fertility Link Navigator lets you filter clinics by which PGT services they offer in-house vs send out, plus typical pricing for your situation.
The bottom line
PGT-A is the most commonly used and most debated; PGT-M and PGT-SR are more clearly indicated for specific genetic situations. Costs range from $3,500 to $15,000+ depending on test, embryo count, and combinations. The right test for the right patient saves miscarriages and time; the wrong test wastes money and can cost you the embryo that would have worked.
Frequently Asked Questions
What is the difference between PGT-A, PGT-M, and PGT-SR? +
PGT-A screens for the right chromosome number, PGT-M tests for a specific inherited single-gene disease, and PGT-SR tests for chromosomal translocations or structural rearrangements.
How much does PGT-A cost? +
USD \$3,500–\$7,500 / CAD \$3,500–\$6,000 for up to about 8 embryos, with per-embryo fees beyond that.
Is PGT-A covered by insurance? +
Rarely outside Progyny-style benefits and a few strong-mandate states. Most patients pay out of pocket in both Canada and the US.
Do I need PGT if I am young and healthy? +
PGT-A is not routinely recommended for under-35 patients with no losses or implantation failure. PGT-M and PGT-SR are indication-driven, not age-driven.
How long do PGT results take? +
Typically 7–14 business days from biopsy to report. Embryos are vitrified during this window.
What is a mosaic embryo? +
An embryo with both normal and abnormal cells. PGT-A reports of mosaicism are increasingly common. Many mosaic embryos can still result in healthy pregnancies — get genetic counseling before discarding them.
