Miller et al 2021_C5_acylcarnitine isobaric separation

Going Beyond AcylCarnitine Profiles

Determine the true cause of acylcarnitine abnormalities detected by newborn screening. Our novel LC-MS/MS acylcarnitine method can separate and individually quantify numerous isobaric/isomeric acylcarnitine species unresolved by traditional flow injection methods. Resolved acylcarnitines include:

  • C3DC/C4OH: malonyl- and hydroxybutyryl/isobutyryl-
  • C4DCs/C5OH: methylmalonyl-, succinyl-, and isovaleryl-
  • C4s: isobutryl- and butyryl-
  • C5s: pivaloyl-, 2-methylbutyryl-, isovaleryl-, and valeryl-
  • C6DCs: adipyl- and 3-methylglutaryl-

Interested in partnering on research studies?

Testing provided by the Biochemical Genetics Laboratory can be commissioned for research studies and applied not only to human plasma/urine/CSF/blood spot cards, but to a wide range of biofluids and tissue extracts derived from model organisms or cell cultures.

How to collect a blood spot sample

Blood spot amino acid testing is an important way to monitor patient diet and treatment. Appropriate collection of blood spot samples can be tricky.  Improper collection can lead to incorrect results. To help make the process easier, we’ve created a short guide to blood spot collection.
