Question

Hematuria can be detected by

• A. red colouration of the urine
• B. black colouration of the urine
• C. glucose in the urine
• D. ketone bodies in the urine

Answer 1

The correct option is A red colouration of the urine

Hematuria is the term given for presence of blood in urine. Urinary tract infections, kidney stones, tumours and cancers can cause discharge of blood along with urine. A notable symptom of hematuria is red coloration of the urine.
Black colouration of urine is due to presence of homogentisic acid in urine. It is an indication of alkaptonuria. Inability of the body's metabolism to breakdown tyrosine and phenylalanine results in accumulation of homogentisic acid in the body.
Glucose in urine is known as glycosuria.
Ketone bodies in urine are due to a clinical condition called ketonuria.
