Genetic examinations list

Filter by name:

PGT – aneuploidy (PGT-A)

Preimplantation genetic testing of aneuploidy in embryos by NGS method to assess their suitability for transfer and exclude non-viable embryos.

Material:

Trophectoderm, Amplified DNA from the trophectoderm

Turnover Time:

4 weeks

STATIM

2 weeks

PGT – structural chromosome defect (PGT-SR)

Preimplantační genetické testování strukturních chromozomových vad u embryí s cílem identifikovat nebalancovaná a aneuploidní embrya a vyloučit je z transferu. Dle typu a velikosti strukturní chromozomové vady se provádí buď metodou NGS, anebo SNP array.

Material:

Trophectoderm, Amplified DNA from the trophectoderm

Turnover Time:

4 weeks

STATIM

2 weeks

PGT – monogenic disease (PGT‐M)

Preimplantation genetic testing of monogenic diseases in embryos by karyomapping (SNP array) to determine their genotype and to test aneuploidy. Embryos carrying a genotype associated with the development of a genetic disorder or a variation in the number of chromosomes are not recommended for transfer.

Material:

Trophectoderm, Amplified DNA from the trophectoderm

Turnover Time:

4 weeks

STATIM

2 weeks

PGT-M direct embryo sequencing

Testing for the presence of a known mutation in an embryo originating from one parent using (Sanger) sequencing of a specific region. Can only be done in conjunction with the PGT-M karyomapping method.

Material:

Trophectoderm, Amplified DNA from the trophectoderm

Turnover Time:

4 weeks

STATIM

2 weeks

PGT of aneuploidy in DEM

Preimplantation genetic testing of aneuploidy in DEM embryos by NGS method to assess their suitability for transfer and exclude non-viable embryos.

Material:

Trophectoderm, Amplified DNA from the trophectoderm

Turnover Time:

4 weeks

STATIM

2 weeks

PRENASCAN

Screening of cell-free foetal DNA (cfDNA) from the blood of a pregnant woman to detect aneuploidy of sex and non-sex chromosomes of the aborted foetus and its gender. From week 10 of the pregnancy.

Material:

Peripheral blood

Turnover Time:

2 weeks

STATIM

1 week
