The "Triage Meter" BNP tests for Brain Natriuretic peptides using which methodology?

Enzyme Immunoassay
Fluorescence Immunoassay
High performance Liquid chromatography
Immunochromatographic assay

Correct Answer

A. Fluorescence Immunoassay

Explanation

The "Triage Meter" BNP tests for Brain Natriuretic peptides using the Fluorescence Immunoassay methodology. This method involves the use of fluorescent labels to detect and measure the presence of specific antigens or antibodies in a sample. It is a highly sensitive and accurate technique that allows for the quantitative measurement of BNP levels in patient samples.

What is the specimen requirement for running the Triage D-dimer?

NaCitrate whole blood or plasma
EDTA whole blood or plasma
Serum

Correct Answer

A. EDTA whole blood or plasma

Explanation

The correct answer is EDTA whole blood or plasma. This means that the specimen requirement for running the Triage D-dimer test is either EDTA whole blood or plasma.

The "Profile-V MedTox Scan Drugs of Abuse" test system uses the following methodology to screen for drugs.

Enzyme Immunoassay
Fluorescence Immunoassay
High performance Liquid chromatography
Immunochromatographic assay

Correct Answer

A. Immunochromatographic assay

Explanation

The "Profile-V MedTox Scan Drugs of Abuse" test system uses the immunochromatographic assay methodology to screen for drugs. This methodology involves the use of specific antibodies that are immobilized on a membrane. When a sample is applied to the membrane, any drugs present in the sample will bind to the antibodies. The membrane is then washed to remove any unbound substances. Finally, a colored indicator is added, which will bind to any drug-antibody complexes present on the membrane. The presence of a colored line indicates a positive result for that particular drug. This assay is commonly used for rapid and qualitative drug screening.

A blue line at the corresponding test (T) position on the MedTox test strip indicates a positive test result.

True
False

Correct Answer

A. False

Explanation

The statement says that a blue line at the corresponding test position on the MedTox test strip indicates a positive test result. However, the correct answer is false. This means that a blue line at the corresponding test position does not indicate a positive test result.

Lipoclear is a substance used to clear grossly lipemic samples of lipids. This is very useful for tests in which lipemia causes interference. Which of the following tests CANNOT be performed after treatment with Lipoclear? Check all that apply.

BUN
CHOLESTEROL
GLUCOSE
TRIGLYCERIDE
CREATININE

Correct Answer(s)

A. CHOLESTEROL
A. TRIGLYCERIDE

Explanation

Lipoclear is used to clear lipemic samples, which means it removes lipids from the sample. Lipids can interfere with certain tests, so Lipoclear is helpful in those cases. Cholesterol and triglyceride tests are specifically mentioned as being affected by lipemia, so they cannot be performed after treatment with Lipoclear. The other tests (BUN, glucose, and creatinine) are not mentioned as being affected by lipemia, so they can still be performed after treatment with Lipoclear.

A grossly hemolyzed serum sample is acceptable for use when testing for HCG with the Sure-Vue Serum/Urine HCG test kit.

True
False

Correct Answer

A. False

Explanation

A grossly hemolyzed serum sample is not acceptable for use when testing for HCG with the Sure-Vue Serum/Urine HCG test kit. Hemolysis refers to the rupture or destruction of red blood cells, which can release substances that may interfere with the accuracy of the test results. Therefore, it is important to use a non-hemolyzed serum sample for HCG testing to ensure reliable and accurate results.

The following specimens are the specimens of choice for optimal performance when using the BinaxNOW Influenza A & B test. (check all that apply)

Nasopharyngeal swab
Stool sample
Nasal aspirate/wash
Whole Blood

Correct Answer(s)

A. Nasopharyngeal swab
A. Nasal aspirate/wash

Explanation

The correct answer is Nasopharyngeal swab and Nasal aspirate/wash. These specimens are the specimens of choice for optimal performance when using the BinaxNOW Influenza A & B test. The test is designed to detect the presence of influenza A and B viruses in these specific samples. Stool sample and whole blood are not recommended specimens for this particular test.

A negative test result using the BinaxNow Influenza A & B test kit does not exclude infection with influenza A and B.

True
False

Correct Answer

A. True

Explanation

The statement is true because a negative test result using the BinaxNow Influenza A & B test kit does not guarantee that a person is not infected with influenza A and B. False negatives can occur due to various reasons such as the sensitivity of the test, timing of the test, or the presence of a different strain of the virus that the test may not detect. Therefore, it is possible for a person to have influenza A or B despite getting a negative result from this particular test.

The "Sure-Vue RF" latex test is used for the quantitative determination of Rheumatoid factor in serum by agglutination of latex particles on a slide.

True
False

Correct Answer

A. False

Explanation

The explanation for the given answer "False" is that the "Sure-Vue RF" latex test is actually used for the qualitative determination of Rheumatoid factor in serum, not the quantitative determination. It works by detecting the presence or absence of Rheumatoid factor through the agglutination of latex particles on a slide. Therefore, the statement in the question is incorrect.
