Convert urobilinogen to stercobilinogen, which is excreted in the faeces as stercobilin and imparts the brown colour to faecal matter.
1, although all the urine parameters were higher in the malarial patients in comparison to the controls, only bilirubin and urobilinogen were statistically significant (p <0.
The presence of bilirubin and urobilinogen indicated liver damage which was also indicated by increased serum bilirubin and liver enzymes.
Some of the bilirubin is reabsorbed back into the body through the bowel wall - eventually appearing in the urine as a substance called urobilinogen (although the typical yellow or orange colour of urine is in fact due a different pigment called urochrome).
0, specific gravity = 1,020, proteins = +++, RBCs = 24/HPF, pus cells = 3-4/HPF, glucose = nil, ketones = nil, bilirubin = nil, urobilinogen = normal, casts = nil.
Urine urobilinogen may also be increased in extreme cases.
The Urisys 1800 (Roche Diagnostics) is a sensitive and specific analyzer for urinalysis, measuring various urine analytes semi-quantitatively, including specific gravity, pH, leukocytes, nitrite, protein, glucose, ketones, urobilinogen, bilirubin and blood (1).
Common evaluation parameters include urine color; clarity; pH; specific gravity; and presence of protein, glucose, ketones, bilirubin, urobilinogen, nitrite, cells (rbc, wbc, epithelial, or renal), crystals, casts, parasites, yeast, bacteria, and sperm.
