You make a 1:5 dilution of a serum sample and measure the urea nitrogen. The analyzer reads that
the concentration of urea nitrogen is 30 mg/dl. What is the urea nitrogen level of the patient's
serum?
35 mg/dl
120 mg/dl
6 mg/dl
180 mg/dl
150 mg/dl - Correct Answer 150 mg/dl
When a dilution is made prior to analyzing a sample, you must multiply that dilution factor with the
reported value to obtain the true level in the sample. In this case, the sample was diluted by a factor
of 5. Therefore, 30 x 5 = 150
