Comment
This term has been used incorrectly for reporting the amount of cholesterol contained in the LDL fraction rather than the amount of the LDL fraction itself, and as of 11/2018, we could not find any major laboratories who are reporting results for each LDL fraction. If testing of LDL fractions becomes common, we will change this term back to Active status.

Change Reason
Seven concepts requested as "Cholesterol.in LDL 1", "Cholesterol.in LDL 2", "Cholesterol.in LDL 3", etc. were mis-stated. At the time these terms were created, there was no such test as "Cholesterol in LDL 1" or any of its siblings. These were intended to be LDL subclasses named LDL 1, LDL 2 and so on, which progress from large buoyant LDL particles to smaller less buoyant ones. We have taken "cholesterol.in" out of the name to reflect the real intention of the submission.
