Test Code:
FPC001
Test Description
FISH - Rapid detection of chromosome 22q microdeletion and the assay offered in conjunction with chromosome study.
Indications for Testing
FISH - The FISH analysis does not detect structural chromosome abnormalities, mosaicism, and other numerical chromosome abnormalities (excluding X, Y, 13, 18, and 21). The American College of Medical Genetics recommends that irreversible therapeutic action should not be initiated on the basis of FISH results alone.
Condition Description
22q deletion syndrome — is a disorder caused when a small part of chromosome 22 is missing.
Test Methods and Limitations
FISH - Fluorescence in situ hybridization (FISH) Fluorescence Microscopy
Detailed Sample Requirements
Products of Conception
| Collection Container(s) | Sterile, screw-top container filled with tissue culture transport medium. |
|---|---|
| Collection | All prenatal specimens will be tested for maternal cell contamination (MCC). Send maternal blood (EDTA tube) for comparison. Transport products of conception and/or fresh tissue (minimum: 10 mg) in a sterile, screw-top container filled with tissue transport medium. Do not place in formalin. If the specimen is too large for a normal collection tube, a larger sterile container can be used. |
| Sample Condition | If the autopsy is performed: Facia lata, diaphragm, tendon, skin, tissue from internal organs (if fresh), chest wall cartilage (particularly if macerated), or placenta from fetal side. If no autopsy is performed: Placenta from fetal side is preferred, e.g., villi. Umbilical cord is also acceptable. State clearly in the TRF whether the tissue was of fetal or placental in origin. |
| Shipping | Shipped immediately at ambient temperature or with a cold pack, especially under hot weather to the laboratory by overnight express with arrival Monday-Friday only. Alternatively, fresh POC and/or tissue samples can be snap-frozen and kept at -80°C. Frozen tissue samples should be shipped overnight on dry ice with arrival Monday-Friday only - NO WEEKEND SHIPMENTS! |
| Special Sample Instructions | For prenatal samples, Revvity Omics will provide a shipping label to use for shipping the sample to our lab. Please call 1 (866) 354-2910 to arrange this. At this time, you will also be connected to a laboratory genetic counselor to answer any questions about the testing. For samples originating outside of the United States, please contact your nearest Revvity Omics laboratory for more information. |
