    Collection
    1) Please call 1-866-GENE-INFO (1-866-436-3463) prior to submission. 2) Parents must be documented carriers of SMA. 3) It is strongly recommended that Maternal Cell Contamination Study, STR Analysis be ordered in conjunction with fetal testing. A separate tube of maternal blood (EDTA) is required for testing. Do not hold cells; forward to laboratory when cells arrive. Amniotic fluid (acceptable): Normal collection procedure. Specimen stability is crucial. Store and ship room temperature immediately. Do not refrigerate or freeze. Amniocyte or Chorionic Villus (CVS) culture (acceptable): Two sterile T-25 flasks, filled with culture medium. Specimen stability is crucial. Store and ship room temperature immediately. Do not refrigerate or freeze. Dissected Chorionic Villus (CVS) biopsy (acceptable): 10-20 mg dissected chorionic villi collected in sterile tube, filled with sterile culture medium. Specimen stability is crucial. Store and ship room temperature immediately. Do not refrigerate or freeze. Do not reject. Forward to performing laboratory for evaluation of sample.

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.
