Sulphosalicylic Acid Test

Materials Required:

Take 2 ml urine sample in a measuring cylinder from the urine sample bottle.
Take a test tube and pour the urine in the test tube.
Using a dropper, take some sulphosalicylic acid.
Add few drops of sulphosalicylic acid in the test tube containing urine. A whitish color appears in the solution.
Using a test tube holder, hold the test tube firmly and heat it gently upon a burner.
A whitish or cloudy turbid solution indicates the presence of albumin in the urine sample.

Take 5 ml concentrated nitric acid in a measuring cylinder from the reagent bottle.
Pour the concentrated nitric acid in a test tube from the measuring cylinder.
Using a dropper, take some urine from the urine sample bottle.
Now incline the test tube and add sample of urine by means of a dropper along the inner side of the test tube so that it forms a layer over the nitric acid.
The presence of white ring at the junction of two layers indicates the presence of albumin in the urine.

You can select the type of test from the ‘Select type of test’ drop down list.
