MRO Review & Interpretation 2

Question 1

A donor's specimen has a creatinine of 18 mg/dL and specific gravity of 1.002. How should the MRO report this result?

Accepted Answer

Report as dilute

Answer

A creatinine between 2 and 20 mg/dL with specific gravity between 1.0010 and 1.0030 meets the criteria for a dilute specimen.

Question 2

During a donor interview, the donor states they took Marinol (dronabinol) by prescription. How does this affect an MRO's review of a THC-positive result?

Accepted Answer

The MRO should verify the prescription and may report negative

Answer

Prescribed Marinol (synthetic THC) is a legitimate medical explanation, and after verification the MRO may report the result as negative.

Question 3

An MRO receives a lab report showing a positive for opiates with morphine at 8,000 ng/mL. The donor claims poppy seed consumption. What is the MRO's correct action?

Accepted Answer

Report positive because the concentration exceeds the level typically explained by poppy seeds

Answer

At concentrations this high, poppy seed consumption is not a scientifically accepted explanation, and the MRO should report the result as positive.

Question 4

A federal agency employee tests positive for amphetamine. The donor presents a valid prescription for Adderall (mixed amphetamine salts). What should the MRO do?

Accepted Answer

Verify the prescription and report negative if legitimate

Answer

A valid prescription for a Schedule II amphetamine product is a legitimate medical explanation allowing the MRO to report negative.

Question 5

The MRO receives a lab report indicating a specimen validity test result of pH 3.0. What is the correct result category?

Accepted Answer

Adulterated

Answer

A pH below 3 or above 11 indicates the specimen has been adulterated because normal physiological urine cannot have such extreme pH values.
