Ordering Recommendation

Use to confirm the causal variant(s) in a fetus with clinical features of a skeletal dysplasia. Predictive testing in a fetus known to be at risk for a skeletal dysplasia based on family history.

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% confluent of cultured amniocytes or cultured chorionic villus sampling (CVS).
AND Maternal Whole Blood 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 amniocytes or cultured CVS filled with culture media. Backup cultures must be retained at the client's institution until testing is complete. If the client is unable to culture amniocytes, this can be arranged by contacting ARUP Client Services at (800) 522-2787 ext. 2141 prior to test submission.
Maternal Whole Blood Specimen: Transport 3 mL whole blood (Min: 2 mL)

Storage/Transport Temperature

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

Unacceptable Conditions
Remarks
Stability

Cultured Amniocytes or Cultured CVS: Room temperature: 48 hours; Refrigerated: Unacceptable; Frozen: Unacceptable
Maternal Whole Blood Specimen: Room temperature: 7 days; Refrigerated: 1 month; Frozen: Unacceptable
