Test Details
Methodology
Spectrophotometry (4-aminoantipyrine)
Result Turnaround Time
2 - 4 days
Turnaround time is defined as the usual number of days from the date of pickup of a specimen for testing to when the result is released to the ordering provider. In some cases, additional time should be allowed for additional confirmatory or additional reflex tests. Testing schedules may vary.
Use
Abnormal phospholipid levels have been associated with obstructive jaundice, abeta- or hypobetalipoproteinemia, Tangier disease, and LCAT deficiency.1
Limitations
This procedure measures lecithin, sphingomyelin, and lysolecithin phospholipids. It does not measure cephalin.
