    10 mL amniotic fluid collected in a sterile plastic leak-proof container · Fasting not stated · Turnaround Set up: Tues

    Method and collection
    Method
    Electrophoresis • Minisequencing • Polymerase Chain Reaction (PCR)
    Collection
    Do not hold specimen; Forward to laboratory when specimen arrives. Amniotic fluid: Normal collection procedure. Specimen stability is crucial. Store and ship at room temperature immediately. Do not refrigerate or freeze; Forward to laboratory when sample arrives. 1. Please call 1-866-GENE-INFO (1-866-436-3463) prior to submission. 2. Documentation of parental carrier status must be provided. 3. It is required that maternal cell contamination study, str analysis be ordered in conjunction with fetal testing. A separate tube of maternal blood (EDTA) is required for this test. Amniocyte or chorionic villus (CVS) culture: Two sterile T-25 flasks, 75% confluent, filled with culture medium. Specimen stability is crucial. Store and ship at room temperature immediately. Do not refrigerate or freeze; Forward to laboratory when cells arrive. Dissected chorionic villus (CVS) biopsy: 10-20 mg dissected chorionic villi collected in sterile tube, filled with sterile culture medium. Specimen stability is crucial. Store and ship at room temperature immediately. Do not refrigerate or freeze; Forward to laboratory when sample arrives.

We compile this page from named laboratory catalogs, guidelines and studies. Labs calculate reference intervals from the people they test, for one assay method and one population group, so an interval describes that population rather than an optimal target.
