A medical student is in a class about specimen analysis. The instructor asks how a lab technician should look for a viral infection in a patient, and the student answers that molecular testing might be helpful.

Which would be the best response from the instructor?

A. “That is incorrect because molecular testing looks at bacteria and not viruses.”

B. “That is correct because molecular testing is very sensitive and can detect even the tiniest organisms, such as viruses.”

C. “That is incorrect because molecular testing analyzes a person’s own DNA and does not look at viruses.”

D. “That is correct because molecular testing can detect viruses and bacteria using molecules made by the immune system.”

explanation:

having a high metabolism at age 13 is not abnormal.   however, if you are concerned, do consult a doctor.   the doctor may identify a correctable issue, and then you'll have your answer.   in the meantime, there are a few steps you might consider.

first, reflect on just how much physical activity (work out and dancing) you are getting relative to your caloric intake.   keep in mind that if you are interested in gaining weight, you must have a higher caloric intake than output.   second, if eating robust healthy meals is not providing enough calories, you'll need to include high caloric, yet healthy, snacks.   i warn against using an over the counter high-calorie supplement (drink or food) until you have consulted a doctor.
