Proven to boost IVF success

Spectrum preimplantation genetic testing (PGT) evaluates embryos for extra or missing chromosomes (PGT-A), single gene conditions (PGT-M), or structural rearrangements (PGT-SR), improving the chances of a healthy pregnancy.

Spectrum tests for chromosomal abnormalities and known inherited genetic condition(s). Sample collections include an embryo biopsy and parental blood/cheek swab. Most results will be returned to your doctor within 5-7 business days.

Spectrum, designed to improve the chance of a healthy pregnancy

Spectrum helps identify the healthiest embryos during an IVF cycle. This helps reduce time to pregnancy and improve the chance of a successful pregnancy, while decreasing the chance of miscarriage or having a child with a genetic condition.


Spectrum PGT offers the following test types:


PGT-A (Aneuploidy) — including haploidy, triploidy, uniparental disomy (UPD), and deletions / duplications


PGT-M (Monogenic / Single Gene Conditions)


PGT-SR (Structural Rearrangements) — including translocations and inversions

Why choose Spectrum SNP microarray with Parental SupportTM?

Proven technology meets peace of mind and simplicity

  • Spectrum SNP PGT is proven to increase the likelihood of a successful pregnancy. Across a range of maternal ages, pregnancy rates are higher when Spectrum is performed with IVF.1
  • Spectrum SNP PGT’s calculated accuracy for each chromosome pair is typically greater than 99%.
  • Natera’s Parental Support™ bioinformatics technology can automatically confirm an embryo matches parental samples and detects non-embryonic DNA contamination. It can also determine parental source of a chromosomal abnormality.
  • Spectrum SNP PGT enables simultaneous PGT-M and PGT-A testing, using a single embryo biopsy sample. PGT-SR can also be performed simultaneously with PGT-A.
