Ordering Recommendation

Confirm diagnosis of a skeletal dysplasia in a symptomatic fetus. Determine if a fetus, that is at risk for a skeletal dysplasia based on a positive family history, is affected.

Mnemonic
SKEL FE
Methodology

Massively Parallel Sequencing

Performed

Varies

Reported

2-4 weeks, if culture is required an additional 1 to 2 weeks is required for processing time.

New York DOH Approval Status
Specimens from New York clients will be sent out to a New York DOH approved laboratory, if possible.
Specimen Required
Patient Preparation
Collect

Fetal Specimen: Four (4) T-25 flasks at 80 percent confluent of cultured amniocytes or cultured CVS. If the client is unable to culture, this can be arranged by contacting ARUP Client Services at (800) 522-2787. 
AND Maternal Cell Contamination Specimen: Lavender (EDTA), pink (K2EDTA), or yellow (ACD Solution A or B).

Specimen Preparation

Cultured Amniocytes or Cultured CVS: Fill flasks with culture media. Transport four (4) T-25 flasks at 80 percent confluent of cultured cells filled with culture media. Backup cultures must be retained at the client's institution until testing is complete.
AND Maternal Cell Contamination Specimen: Transport 3 mL whole blood (Min: 1 mL)

Storage/Transport Temperature

Culture Amniocytes or Cultured CVS: CRITICAL ROOM TEMPERATURE. Must be received within 48 hours of shipment due to lability of cells.
Maternal Cell Contamination Specimen:
Room temperature.

Compliance Statement C: For human genetic inheritable conditions and mutations. This test was developed and its performance characteristics determined by ARUP Laboratories. The U. S. Food and Drug Administration has not approved or cleared this test; however, FDA clearance or approval is not currently required for clinical use. The results are not intended to be used as the sole means for clinical diagnosis or patient management decisions.

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

Note

Reported times are based on receiving the four T-25 flasks at 80 percent confluent. Cell culture time is independent of testing turn-around time. Maternal specimen is recommended for proper test interpretation. Order Maternal Cell Contamination.
