Ordering Recommendation

Consultation with a genetic counselor is advised. Order for fetal testing to detect a previously characterized variant in a family member.

Specimen Required

Patient Preparation

Contact ARUP's genetic counselor at (800) 242-2787 extension 2141 prior to test submission.
Fetal Specimen
: Two T-25 flasks at 80 percent confluent of cultured amniocytes. If the client is unable to culture amniocytes, this can be arranged by contacting ARUP Client Services at (800) 522-2787. Or amniotic fluid.
AND Maternal Specimen:
Lavender (EDTA), pink (K2EDTA), or yellow (ACD Solution A or B).

Specimen Preparation

Cultured Amniocytes: Fill flasks with culture media. Transport two T-25 flasks at 80% confluent of cultured amniocytes. Backup cultures must be retained at the client's institution until testing is complete.
OR Amniotic Fluid:
Transport 10 mL unspun fluid. (Min: 5 mL)
AND Maternal Specimen:
Transport 3 mL whole blood. (Min: 1 mL)

Storage/Transport Temperature

Cultured Amniocytes: CRITICAL ROOM TEMPERATURE. Must be received within 48 hours of shipment due to liability of cells.
Amniotic Fluid:
Room temperature.
Maternal Specimen:

Unacceptable Conditions

Maternal specimen is recommended for proper test interpretation. Order Maternal Cell Contamination, Maternal Specimen. This can be arranged by contacting ARUP genetic counselors at (800) 242-2787 ext. 2141.


Fetal Specimen: Ambient: 48 hours; Refrigerated: Unacceptable; Frozen: Unacceptable

Interpretive Data

For quality assurance purposes, ARUP Laboratories will confirm the above result at no charge following delivery. Order Confirmation of Fetal Testing and include a copy of the original fetal report (or the mother's name and date of birth) with the test submission. Please contact an ARUP genetic counselor at (800) 242-2787 extension 2141 prior to specimen submission.

This test was developed and its performance characteristics determined by ARUP Laboratories. It has not been cleared or approved by the US Food and Drug Administration. This test was performed in a CLIA certified laboratory and is intended for clinical purposes.

Counseling and informed consent are recommended for genetic testing. Consent forms are available online.

Compliance Category

Laboratory Developed Test (LDT)


Documentation of the familial gene mutation(s) is required to perform targeted sequencing. Submit a copy of a relative's laboratory test report documenting the gene and specific mutation(s) for which testing is requested.

This test is available for genes currently sequenced at ARUP: APC, BRCA1, BRCA2, CFTR, G6PD, GJB2, HBA1/HBA2, MLH1, MSH2, MSH6, MECP2, PMS2, PTEN, HBB, MEFV, ACADM, PRSS1, and known familial variants. . Some genes will require approval before fetal testing can begin. Contact ARUP's Genetic Counselors at (800) 242-2787 extension 2141 prior to test submission.

Submit a positive control with the patient specimen for appropriate interpretation. Disease-specific patient history forms are available at www.aruplab.com/Testing-Information/consentforms-patienthistory.jsp
