Special Instructions
The following information must be provided with the test request form: patient's date of birth, gestational age, and additional patient demographic information: pregnancy type (singleton), donor egg status and the clinical indications including advanced maternal age and other indications. Samples must be shipped in a Sequenom collection kit to maintain integrity.
Limitations
While the results of these tests are highly accurate, discordant results may occur due to factors such as placental, maternal, or fetal mosaicism; prior maternal organ transplant; or maternal neoplasms. The test is not validated for multiple gestations and multifetal samples are excluded from processing. These are screening tests and should not replace prenatal diagnosis methods such as CVS or amniocentesis. Factors affecting the results include maternal BMI, systemic conditions like lupus, and certain pharmaceuticals. Results should be discussed with a qualified healthcare provider and should not be solely used for pregnancy management decisions.
