Occult Blood Microscopy Random Urine
What is this test?
Occult Blood Microscopy Random Urine Test is performed to determine whether invisible (occult) blood is present in the urine.
Importance of this test:
The presence of occult blood cannot be identified with the naked eye. Presence of occult blood in the urine may be a sign of kidney disease, urinary tract infection, or liver disease. Normally, the urine does not contain blood because the kidneys prevent blood from entering the urine. Therefore, the presence of occult blood in the urine may indicate that your kidneys are not working properly. The condition of the presence of blood in urine is known as hematuria. This test helps to determine the presence of red or white blood cells in the urine.
Why this test is performed?
