Exercise 57

The primary reason for performing a Clinitest is to:

A. Check for high ascorbic acid levels

B. Confirm a positive reagent strip glucose

C. Check for newborn galactosuria

D. Confirm a negative glucose reading

Step 1 of 2

Clinitest:

Clinitest is the earlier test to detect urine glucose by copper reduction method.

• In the presence of heat and alkali, glucose and other substances ability to reduce copper sulfate to cuprous oxide is calculated.

• Reducing substances and also reducing sugars are measured in non-specific test of clinitest.

• Reducing sugar include fructose, pentose, lactose and galactose.

• Galactose is significant clinically.

• Urine galactose (galactosuria) in new born is an inborn error of metabolism where consumed galactose break down is prevented by galactose -1- phosphate, uridyl transferase.

• Clinitest is performed on patients up to the age of 2 years.

Therefore, to “check new born galactosuria” is the primary reason to perform clinitest Hence, the correct answer is option.
