  • IVD/CE Conformity to directive 98/79/CF
  • Sample to result in less than 3 hours.
  • Tested on 43,000 Clinical samples denoting its diagnostic accuracy
  • Only product on the market with 4 pseudoautosomal markers for XY and mosaic aneuploidy cases
    (See Protocol for complete list of case examples)

  • Amniotic Fluids, Chorionic Villus, Fetal blood, Neonatal & Adult blood/tissues




The two Multiplexes QF-PCR Sets S1 and S2 allow simultaneous analysis of five STRs on each of the autosomes 21, 18 and 13 in addition to three pseudoautosomal (DXYS267, X22 and DXYS218) and one X-linked STRs. Two non-polymorphic sequences, Amelogenin (AMXY) and SRY, are independently amplified for sexing.

Chromosome-specific back-up marker sets are also available. MXY contains seven STRs and two sexing markers on the sex chromosomes. In addition, the paralogous sequence TAF9L on chromosome 3 and X allow accurate assessment of chromosome X dosage in all cases independently from frequency calculation (see further below). M21, M13 and M18 contain five STRs on each of chromosomes 21 and 18, and four markers on chromosome 13. The back-up sets may be used either independently or in cases where all the S1 and S2 markers on any one of these chromosomes have been found to be uninformative (homozygous).

Extra markers not included in S1 and S2 are labelled*. Note that in each chromosome-specific set two markers amplified in S1 and S2 are repeated. This provides an opportunity to confirm sample identity. Any discrepant results with respect to these markers, shared in common between the S1/S2 and the chromosome-specific back-up marker sets, should be a matter of concern. The chromosome-specific back-up sets may also be used to confirm any abnormal results.
