Exercise 27

The primary advantage of a first morning specimen over a random specimen is that it:

A. Is less contaminated

B. Is more concentrated

C. Is less concentrated

D. Has a higher volume

Step 1 of 2

First morning specimen:

First morning specimen are collected immediately after waking up in the morning.

• The specimen collected in the morning will have chemicals and elements. So, the specimen is more concentrated.

• It is more advantageous to analyze the chemicals.

• Advantages of the first morning specimen are,

o More concentrated

o Contamination is low

o High volume

Random specimen:

• Random specimen is collected from patient randomly at any time, so the specimen is dilute and less concentrated.

Therefore, first morning specimen “is more concentrated” which is a primary advantage than random specimen. Hence, the correct answer is option.
