|Test||CHOLESTEROL, HDL, SERUM|
|Description||HDL cholesterol is inversely related to the risk of developing coronary artery disease. A low HDL/LDL cholesterol ratio is directly related to the risk of developing coronary artery disease. A high HDL cholesterol is associated with the "longevity" syndrome.
NOTE: Acetaminophen concentrations at toxic levels and high doses of N-Acetylcysteine (NAC) used to treat acetaminophen intoxication can falsely lower the result of this test.
NOTE: This test, when ordered on Medicare patients, is subject to the National Coverage Determination (NCD) policy "Lipids Testing". Please verify that the diagnosis code (ICD-9) you have chosen demonstrates medical necessity for the test as documented in the physician's patient record. The CMS web site or the NorDx Limited Coverage Documentation Guide are available to assist you with this verification. A properly executed Advance Beneficiary Notice (ABN) must be submitted with the specimen if medical necessity is not demonstrated by the ICD-9 code chosen.
