Urobilinogen. Urobilinuria was identified in 184 (30.6%) of 602 patients; it was associated with higher bilirubin in urine and proteinuria (P < 0.05).
Neonates have a largely sterile gut, so the conversion to urobilinogen is poor, and there is increased reabsorption of bilirubin.
falciparum infection urinary bilirubin and urobilinogen were significantly higher at higher malaria parasitaemia.
rapid tests for analysis of ph, protein, glucose, blood, nitrites, ketones, bilirubin, urobilinogen, specific density, leukocytes in the urine, 3 pcs.

A urine test showed 2+ urobilirubin and negative urobilinogen. The feces had a normal appearance with negative occult blood.
The most common tests include bilirubin, urobilinogen, glucose, ketones, protein, blood, nitrite, leukocyte esterase, and pH.
Urinalysis may reveal hemoglobinuria and urobilinogen. Both clinicians and pathologists should understand that cold autoantibodies have the ability to interfere with hematology-based testing, rendering the only reliable component in a complete blood cell count to be the hemoglobin.
The urinalysis test items were glucose, bilirubin, ketone bodies, specific gravity, occult blood, pH, proteins, urobilinogen, nitrites, and leukocytes.
Urine results in Table 2 demonstrate elevated levels of urobilinogen, the abnormal presence of ketones, microalbumin and proteins, and an increased specific gravity.
Lack of interference by medications and urobilinogen with ion exchange methods has been demonstrated previously (5-7).
Qualitative (protein, sugar, urobilinogen, epithelial cells, pus cells, RBCs, hemoglobin) and quantitative (volume, pH and specific gravity) evaluations were conducted on urine samples.
