isotope labelled standards
availability of panel of ceramides and scores, which renders easier interpretation by clinicians
|
expensive test
spectrometry instrumentation expensive
expert and trained personnel needed
difficulties in result interpretation
not widespread in clinical laboratories
|
|
lack of reference ranges,
lack of standardization,
lack of control quality schemes
lack of identification of key ceramides and panels/scores and the knowledge of their biological effects in different cardiometabolic conditions
evaluation of additive ceramide value over and beyond conventional biomarkers and CV scores
intra- and inter-biological variability to be assessed
|
|
identification of serum ceramide determinants needed (e.g., gender, age, circadian rhythm, and lifestyle)
the extraction phase of the sample is operator-dependent
possible ionic suppression caused by the nature of the matrix
