Fatty Acid Oxidation Disorder Laboratory | Pediatric Genetics

果冻影院 and Children's Research Institute Fatty Acid Oxidation Disorder Laboratory

These are the diagnostic services available in the Fatty Acid Oxidation Disorder Laboratory at the 果冻影院 and Children’s Wisconsin. For almost 18 years, we have offered these services to geneticists, endocrinologists, gastroenterologists and neurologists around the country. Using radio-HPLC, we can now define the characteristic diagnostic profiles of accumulated fatty acylcarnitines in cultured fibroblasts from affected patients and can also detect isovaleric acidemia, all subtypes of propionic and methylmalonic acidemias and β-ketothiolase deficiency. At present, we offer β-oxidation enzyme immunoblotting in fibroblasts, liver and other tissues for many of the polypeptides involved in the β-oxidation spiral. We have also performed many successful prenatal diagnoses for these disorders in cultured amniocytes. The unique panel of diagnostic tests we offer is summarized below.

My group also collaborates closely with other major North American, European, Japanese and Australasian academic groups concerned with the diagnosis, treatment, and investigation of fatty acid oxidation disorders. I am board certified in Clinical Biochemical Genetics and Clinical Genetics and the laboratory is accredited by CAP, JCAHO and registered under CLIA. Please call, email or fax me if you want additional testing information or wish to discuss individual patients.

Requisition Form and Billing Information

Please download the Fatty Acid Oxidation Disorders Screening Tests Requisition Form (PDF) and include in the shipment of the skin fibroblasts.

Patient and Billing Information
For cultures sent by mail to our laboratory, we only bill the referring hospital or laboratory for these tests. We suggest having the Department of Pathology in your hospital send the sample to us. The requisition form should be included with fibroblast cultures and clinical and biochemical information.

Shipping Instructions, Pricing and CPT Codes

Monday through Thursday
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 尾-oxidation, excluding riboflavin-responsive variants and all methylmalonic acidemias: $998.25 (CPT codes 82017+88233+82542), with physician interpretation (CPT code 80500).

Prenatal Diagnosis
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.

3H-Acyl-carnitine profiling by radio-HPLC in amniocytes to screen for all known disorders of 尾-oxidation, excluding riboflavin-responsive variants and all methylmalonic acidemias: $998.50 (CPT codes 88235+82542), with physician interpretation (CPT code 80500).

These analyses are non-experimental, non-investigational and not in conflict with medical standards. This laboratory and Children's Wisconsin has been accredited by the Joint Commission on Accreditation of Healthcare Organizations, the College of American Pathologists, CLIA (52D0661957), and HCFA (license number 16-0058). Dr. Rhead is board-certified in Clinical Biochemical Genetics by the American Board of Medical Genetics.

Explanation of CPT Codes:

88233 Skin fibroblast culture
82492 Chromatography, quantitative, column (e.g., gas liquid or HPLC); multiple analytes, single stationary and mobile phase
88235 Tissue culture for non-neoplastic disorders; amniotic fluid or chorionic villus cells
80500 Physician interpretation
88372 Protein analysis of tissue by Western Blot, with interpretation and report, one band
