10-200 mg of STERILE chorionic villi, other fetal tissue or other tissue (or 1cm x 1cm or 2 mm punch biopsy), place in STERILE transport medium in STERILE leak-proof tubes.
Collection personnel MUST initial specimen container to confirm sample identity.
Minimum Collection Volume
25 mg of chorionic villi or other tissue in sterile culture medium is needed for 14 day turn around time (TAT).
or
1cm x 1cm or 2 mm punch biopsy in sterile culture medium.
If a lesser volume of chorionic villi or tissue is sent, the laboratory will attempt to perform the test requested. The laboratory cannot assure either a result and/or the ability to perform repeat testing and/or additional testing if the minimum volumes are not met.
Stability (from collection to initiation)
Label tubes with patient name and date of birth (DOB).
Patient Preparation
For products of conception (POC) the preferred tissue is chorionic villi. If fetal tissue is sent, please ALSO send chorionic villi, if available.
The lab can provide tubes of transport medium - Call (513) 636-4474.
DO NOT USE FORMALIN, the tissue must be fresh and sterile in order to obtain cell growth.
Storage/Transport Temperature
