Outcome Measures

Primary Outcomes (2)

  • Determination of sensitivity of NIPT detection of trisomy 21 among a population of women with twin gestations.

    time from maternal blood draw to delivery

  • Determination of specificity of NIPT detection of trisomy 21 among a population of women with twin gestations.

    time from maternal blood draw to delivery

Study Arms (1)

Pregnancies with multiple gestations

Device: MaterniT21 PLUS and GENOME Laboratory-Developed Tests

Interventions

Both the MaterniT21 PLUS and GENOME are intended for use as laboratory developed test that analyze ccfDNA extracted from a maternal blood sample utilizing Massively Parallel Sequencing (MPS) technology.

Pregnancies with multiple gestations

Eligibility Criteria

Age18 Years+
Sexfemale
Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
Study Population

The Study Population will consist of women 18 years of age and older who underwent testing with a Sequenom NIPT, were pregnant with a multiple gestation at the time of testing and whose pregnancies should have outcome based upon gestational age at the time of testing.

You may qualify if:

  • subject pregnant with a multiple gestation and received NIPT from Sequenom Laboratories;
  • subject was 18 or older at the time of NIPT

You may not qualify if:

  • none
