Question

A serum sample had an elevated glucose level so a dilution of 1 part plasma and 2 parts saline was made. The value of the diluted sample was 250 mg/dl. What value is the true reportable value for this patient's test?

		250 mg/dl
		500 mg/dl
		300 mg/dl
		750 mg/dl

Answer 1

A serum sample is diluted to increase the correctness of tge analyte being tested and decrease its concentration.

The diluted sample's serum glucose level was=250mg/dl. The dilution was done by adding 1part of plasma and 2 parts of saline . So the Dilution factor = 1:2

True reportable value of the patient = determined value multiplied by dilution factor

True value = D. F *Determined value. = [1:2] * 250 mg/dl. = 2* 250 mg/dl = 500 mg/dl

So 0ption "B" is the correct option
