Clinical Utility:
Myasthenia gravis (MG) is the most common neuromuscular transmission disorder. It is an antibody mediated autoimmune disease that stems from a loss of acetylcholine receptors (AChR) at neuromuscular junctions. ACh Rautoantibodies are diagnostic of MG, and are found in 80-90% of MG patients. A small portion of patients with early onset of ocular restricted MG may only have AChR modulation autoantibodies, thus if AChR binding autoantibodies are absent in a patient with weakness or ocular symptoms consistent with MG, AChR modulationg autoantibodies should be ordered.

Cirrhosis in a child should raise consideration of AAT deficiency or Wilson’s disease.

Clinical Utility:
Low concentrations of apolipoprotein A-1, the major protein of high density lipoproteins (HDL), are more useful than HDL cholesterol, cholesterol or triglycerides in identifying individual patients with angiographic coronary-artery disease. Low concentrations of apolipoprotein A-1 are also more indicative of CAD when studied in survivors of myocardial infarction.

Clinical Utility:
LDL and its major protein, apolipoprotein B, play an essential role in lipid transport and metabolism. Apo B may regulate cholesterol synthesis through its interaction with specific cell membrane receptors and by inhibition of HMG Co A reductase. This enzyme has been identified as the rate controlling enzyme in cholesterol biosynthesis. Apo B may be important in the genesis of atherosclerosis and its quantitation useful in the evaluation of patients at risk for or having coronary atherosclerosis (CAD). High levels indicate increased risk for CAD.
