Cardio IQ® Omega-3 and -6 Fatty Acids

Test Code: 91734

Methodology: Chromatography/Mass Spectrometry
This test was developed and its analytical performance characteristics have been determined by Quest Diagnostics Nichols Institute, San Juan Capistrano, CA. It has not been cleared or approved by the FDA. This assay has been validated pursuant to the CLIA regulations and is used for clinical purposes.

Includes: Omega-3 (EPA+DHA) Index, Omega-6/Omega-3 Ratio, EPA/Arachidonic Acid Ratio, Arachidonic Acid, EPA, DHA

CK-MB Index

Test Code: 59221

Methodology: N-acetyl-L-cysteine (NAC) and Immunoassay followed by ratio determination

Includes: Creatine Kinase total, CK-MB, CK-MB Index

Clinical Significance: CK-MB is normally undetectable or very low in the blood. If CK-MB is elevated and the ratio of CK-MB to total CK (relative index) is more than 2.5-3, then it is likely that the heart was damaged. A high CK with a relative index below this value suggests that skeletal muscles were damaged.

Troponin I

Test Code: 59039

Methodology: Chemiluminescent Microparticle Immunoassay (CMIA)

Clinical Significance: Troponin I is part of a protein complex which regulates the contraction of striated muscle. In acute coronary syndromes (ACS), it can be detected in blodd at 4-8 hours following the onset of chest pain, reaches a peak concentration at 12-16 hours, and remains elevated for 5-9 days. Troponin I has been used as a reliable marker in the diagnosis of perioperative myocardial infarction in patients undergoing cardiac surgery.

C-reactive Protein

Test Code: 4420

Methodology: Nephelometry

Limitations: Oral contraceptives, IUDs, pregnancy, and menstruation may raise CRP levels. Levels are lowest during ovulation.

Clinical Significance: Increased CRP levels are found in inflammatory conditions including: bacterial infection, rheumatic fever, active arthritis, myocardial infarction, malignancies and in the post-operative state. This test cannot detect the relatively small elevations of CRP that are associated with increased cardiovascular risk.

Creatine Kinase (CK), Total

Test Code: 374

Methodology: Spectrophotometry (SP)

Clinical Significance: Test for myocardial infarction and skeletal muscle damage. Elevated results may be due to: myocarditis, myocardial infarction (heart attack), muscular dystrophy, muscle trauma or excessive exercise.

Alternative Name(s): CK, CPK

Includes: Antithrombin III Activity

Alternative Name(s): Antithrombin III Functional; AT-3 Activity; AT3
