Cholesterol levels do not fluctuate as triglycerides, fatty acids, lipoproteins, and chylomicrons do after an individual eats a meal. This is the reason that patients are told to fast; the laboratory needs a fasting sample to determine a lipid profile or panel which includes the latter four components.
Which of the following lipid tests is LEAST affected by the fasting status of the patient?

• A.Triglycerides
• B.Cholesterol
• C.Fatty acids
• D.Chylomicrons
• E.Lipoproteins

Myoglobin rises typically within 2-4 hours after a myocardial infarction and stay elevated for days, with a peak at the 6-9-hour mark post-MI. After myoglobin, troponin is the next fastest to rise afer a mycardial infarction and can rise within 3-4 hours with a peak around 12 hours post-MI. LD (8-12 hours, 24-48 hour peak) and CK (4-6 hours with peak at 24-36 hours) will also rise after MI, but are not as fast to rise as myoglobin and troponin.
Chemistry
A patient is admitted to the hospital with acute chest pain, but which of the following cardiac markers will be elevated FIRST if the patient had an MI?

• A.LD
• B.CK
• C.Myoglobin
• D.Troponin

Electrophoresis uses an electric field to separate molecules based on differences in net electrical charge. The rate of electrophoretic migration is also dependent on the ionic radius of the molecule, the viscosity of the solution through which it is migrating, the electrical field strength, temperature, and the type of supporting medium used.
Electrophoretic separation fundamentally relies on:

• A.Net charge differences of molecules
• B.Concentration differences of molecules
• C.Size differences of molecules
• D.Shape variations of molecules

A negative glucose oxidase test and a positive test for reducing sugars in urine indicates the presence of a non-glucose reducing sugar such as galactose, fructose, glyceraldehyde, etc. This is the reason that certain patient populations require additional confirmatory sugar testing on their urine samples.
A negative glucose oxidase test and a positive test for reducing sugars in urine indicates:

• A.A false-negative glucose oxidation reaction
• B.The presence of a non-glucose reducing sugar such as galactose
• C.True glycosuria

The role of provider-performed microscopy (PPM) is the

• A.Specific microscopic tests (wet mounts) performed by a physician for his or her own patients.
• B.Means by which quality control between laboratories is maintained.
• C.both moderately and highly complex
• D.Process of performing laboratory testing at the bedside of the patient and a means of decentralizing some of the laboratory testing.
