Special Instructions

For test inquiries, call CMBP genetic services at 800-345-4363. Patient must have submitted a previous specimen in the first trimester for the Serum Integrated 1 [017200] test. Gestational age will be based on information provided with the first trimester specimen. Patient information may be provided to the laboratory using the Maternal Prenatal Screening requisition 0900. Testing is provided from 15.0 to 21.9 weeks of gestation.

Limitations

Serum integrated screening requires two specimens: one collected in the first trimester and one in the second trimester. This test number is for the second trimester portion of the test. This is a screening test. A positive result means that diagnostic testing may be offered to the pregnant woman to determine if a neural tube defect or chromosome abnormality is present.

This test was developed and its performance characteristics determined by Labcorp. It has not been cleared or approved by the Food and Drug Administration.
