3Please note: Clinical mutation analysis for GA I, GA II (MADD) and VLCADD (VLCAD) is performed by the DNA Diagnostic Laboratory.

4Tissue specimens must be immediately frozen on dry ice, stored at -70oC, and shipped frozen on dry ice. In both the regular assay and the microassay, six assays are performed — all with the same CPT code. Microassay (available on liver only) is required for specimens of less than 60 mg.

5Cost is $330 for each parent (enzyme assay only). 6.0 ml pediatric minimum, or 10.0 ml adult minimum, of whole blood is required. Collect blood in purple cap (EDTA) tubes. Please be aware that vacuum blood collection tubes rarely collect the entire volume indicated on the tube, and additional tubes may be required to achieve the actual minimum volume required. Store and ship on wet ice (not frozen). Call this laboratory before shipping.

6proband only. No parents. Please do not include an unrelated control when ordering the combined test. 6.0 ml pediatric minimum, or 10.0 ml adult minimum, of whole blood is required. Collect blood in purple cap (EDTA) tubes. Please be aware that vacuum blood collection tubes rarely collect the entire volume indicated on the tube, and additional tubes may be required to achieve the actual minimum volume required. Store and ship on wet ice (not frozen). Call this laboratory before shipping.
