Important Note

Please accompany specimen with Iowa Maternal Screen Test Request Form.

Can be performed without a 1st trimester nuchal translucency (NT) measurement, but a NT measurement is preferred.

Incorrect information, especially incorrect dating, will result in inaccurate risk assessment.  Requires nuchal translucency (NT) measurement by sonographer certified by FMF or NTQR.  The sonographer's name, certification number, and certifying organization must be on file with the laboratory to submit a NT measurement.  Call 319-335-4056 the first time a sonographer is submitting a NT measurement with a test request.  If NT is unobtainable, order Intergrated Screen.  The following information is required for test interpretation: Ultrasound date AND crown rump length (CRL) measurement, a NT measurement obtained between 10 weeks 0 days and 13 weeks 6 days is preferred, but not required, patient's date of birth, current weight, patient's race, if patient requires insulin, family history of NTD, and for IVF pregnancies, the age of the egg donor at time of egg retrieval.  This test cannot be performed on multiples.  Detection rates: 85% Down Syndrome 80% Trisomy 18 85% Neural Tube defects.  False positive Rate: 2.6 % without NT 1.9% with NT. Results are available after the second serum sample is processed.  If the second specimen is not received for sequential screening, the results are uninterpretable and no maternal risk will be provided.
