Acylcarnitine Profile, Quantitative, plasma or serum !!! NOTE: The contents are valid only for: 07/04/2025 !!!
| WSLH Department: | Biochemical Genetics |
| WSLH Test Code: | BG00540 |
| Day(s) Performed: | Prior to submission of specimens for Biochemical Genetics testing, please contact the laboratory at: (608) 263-4619. |
| Turn-around Time: | Within 10 working days after receipt of the specimen |
| Recommended Uses: | Measurement of acylcarnitine species in plasma/serum is important in the diagnosis and clinical management of patients with an organic acidemia or fatty acid oxidation defect. Clinical information is particularly important for appropriate interpretation. |
| Pre-approval: | N |
| Contraindications: | None |
| Additional Tests Performed: |
|
| Preparation for Collection: | |
| Specimen Requirements: | Minimum 0.5 mL of plasma or serum |
| Collection Instructions: | Preferred green top tube with either Sodium Heparin or Lithium Heparin additive or serum separator tube. Draw 2.5 times the volume requested. Gently invert the tube no more than eight times. Further inversion my cause loss of sample integrity. Separate plasma by centrifugation. For serum, do not centrifuge immediately after collection. Allow the blood to clot at least 30 minutes, but no more than 1 hour before centrifugation. Transfer the plasma or serum to plastic screw top freezer vial. Freeze the specimen as soon as it is separated from red blood cells. Do not ship frozen plasma or serum in glass tubes. |
| Collection Kit/Container: |
Serum Separator Tube (red top) or Heparin Tube (green top)
