Though automated extraction machines have many benefits over manual methods the costs are high and generally require a high throughput of samples in order to justify the costs.
Automated extraction has many benefits over the traditional manual methods. The most important benefit is that the nucleic acid isolated is constantly consistent. There is a reduced amount of manipulation with dramatically decreases the chance of cross contamination. Also, automated extraction machines are considered moderate complexity and can be performed by a wider variety of laboratory professionals.
All of the following are considered benefits of automated isolation and extraction equipment EXCEPT:

A. Automated isolation equipment is cheaper and more practical

B. Automated isolation equipment requires less manipulation

C. Automated isolation equipment is considered moderate complexity

D. Automated isolation equipment provides consistent results

Epidemiology studies only infectious diseases that impact humans

A. True

B. False

A slow, progressive drift of values away from the mean is called a trend. Trends occur when a particular analyte value slowly and progressively changes in one direction from one run to the next. Monitoring data for trends is part of good laboratory practice and is one indicator of many that helps laboratorians determine whether the measurement system is fucntioning appropriately.
A slow, progressive drift of values away from the mean is called a:

A. Coefficient of Deviation

B. Dispersion

C. Trend

D. Variance

E. Sh

Pink or Red stopper tubes can be used for Blood Bank!

A. True

B. False

After collection all blood should be stored at 1 - 6oC, unless it is going to be used as a source of platelets.
A refrigerator used to store whole blood must be able to maintain a temperature in the ranges of:

A. 0 - 4 degrees Celsius

B. 2 - 4 degrees Celsius

C. 2 - 8 degrees Celsius

D. 1 - 6 degrees Celsius

Triglyceride blood concentrations change significantly when you eat, as opposed to relatively stable levels of cholesterol, HDL, or LDL circulating in the blood. Whenever you eat a meal that contains fat, your triglyceride levels rise, which is why it is important to have a patient fast before the sample is collected.
Which of the following lipid results would be expected to be FALSELY elevated on a serum specimen from a non-fasting patient?

A. cholesterol

B. triglyceride

C. HDL

D. LDL (not calculated)

The laboratory is under the direction of a:

A. phlebotomist

B. pharmacist

C. medical assistant

D. pathologist

Heparin is the additive of choice for blood gas syringe collection as it has the least amount of interference with the blood gas analytes measured.
Which of the following additives should be used for the collection of a sample for blood gas analysis:

A. Sodium citrate

B. EDTA

C. Sodium oxalate

D. Heparin

The end of the initial phase of HH treatment is considered when the serum ferritin decreases to between 20 and 50 ng/mL.
What is a typical finding for determining the endpoint for the initial or iron-depletion phase of treatment for hereditary hemochromatosis (HH)?

A. The serum ferritin decreases to between 20 and 50 ng/mL

B. The hepatic iron index returns to normal

C. The transferrin saturation drops below 20%

D. The serum iron falls to below 35 g/dL.

A positive spot test shows agglutination of horse erythrocytes when added to patient serum previously absorbed with guinea pig kidney, but not when added to patient serum previously absorbed with beef erythrocyte stroma. The test is generally simple, sensitive, and specific, but false negative are common in young children with mononucleosis. The most common rapid slide test (MONOSPOT©) for infectious mononucleosis employs:

A. Horse erythrocytes

B. Sheep erythrocytes

C. Intact beef erythrocytes

D. None of the above

Hybridization is a technique used to determine presence of target DNA or RNA by adding a synthetic strand that binds by complementary base pairing to the target.
Microbiology
In molecular diagnostic testing, hybridization employs complementary base pair binding of a synthetic strand to DNA or RNA.

A. True

B. False
