Ship two T-25 (25cm2) flasks of confluent fibroblasts obtained from skin biopsy and routine fibroblast tissue culture to the above address by overnight express accompanied by clinical and biochemical data and the billing information sheet.
3H-Acyl-carnitine profiling by radio-HPLC in intact cultured fibroblast monolayers to screen for all known disorders of β-oxidation, excluding riboflavin-responsive variants and all methylmalonic acidemias: $969.75(CPT codes 88233 + 82017 + 82486), including physician interpretation (CPT code 80500).
Immunoblotting for short-, medium-, long-, and very-long chain acyl-CoA dehydrogenase and α- and β- electron transfer flavoprotein subunits in fractionated cultured fibroblasts: $726.75 for any of the above polypeptides (CPT codes 87252 + 86334 + 83894 + 88346 + 84165), including physician interpretation (CPT code 80500).
Prenatal diagnosis on amniocytes is possible for virtually all fatty acid oxidation disorders. However, before we will accept amniocyte samples from a referring laboratory, please contact William J. Rhead, MD, PhD directly at
414-266-2906. In addition to 2 confluent T-25 flasks of amniocytes from the proband fetus, we require amniocytes from 2 anonymous control pregnancies, 2 T-25s each. Further details can be obtained directly from Dr. Rhead.
These analyses are non-experimental, non-investigational and not in conflict with medical standards. This laboratory and Children's Hospital of Wisconsin has been accredited by the Joint Commission on Accreditation of Healthcare Organizations, the College of American Pathologists, CLIA (16D0664504), and HCFA (license number 16-0058). Dr. Rhead is board-certified in Clinical Biochemical Genetics by the American Board of Medical Genetics.
