In medicine, bilirubinuria is an abnormality in which conjugated bilirubin is detected in the urine. [1] The term "biliuria" is very similar, but more general. It refers to the presence of any bile pigment in the urine. Conjugated bilirubin is detected in urine at bilirubinemia of approximately 30-34 mmol/L or 2 mg/dL.
Q is the urine flow (volume/time) [mL/min] (often [mL/24 h]) C B is the plasma concentration [mmol/L] (in the USA often [mg/mL]) When the substance "C" is creatinine, an endogenous chemical that is excreted only by filtration, the clearance is an approximation of the glomerular filtration rate .
Hematuria can be classified according to visibility, anatomical origin, and timing of blood during urination. [1] [6]In terms of visibility, hematuria can be visible to the naked eye (termed "gross hematuria") and may appear red or brown (sometimes referred to as tea-colored), or it can be microscopic (i.e. not visible but detected with a microscope or laboratory test).
In biomedical contexts, a biomarker, or biological marker, is a measurable indicator of some biological state or condition. Biomarkers are often measured and evaluated using blood, urine, or soft tissues [1] to examine normal biological processes, pathogenic processes, or pharmacologic responses to a therapeutic intervention.

However, the increased uric acid levels in urine can contribute to kidney stones. Thus, use of these drugs is contraindicated in persons already with a high urine concentration of uric acid (hyperuricosuria). In borderline cases, enough water to produce 2 liters of urine per day may be sufficient to permit use of an uricosuric drug.
A leukocyte esterase test (LE test) is a urine test for the presence of white blood cells and other abnormalities associated with infection. White blood cells in the urine can indicate a urinary tract infection (UTI). Positive test results may be clinically significant in the right context.
Frequent urination, or urinary frequency (sometimes called pollakiuria), is the need to urinate more often than usual. Diuretics are medications that increase urinary frequency.
