For a stay longer than 180 days, the flat-rate per diem is 55 percent. Rates are fixed, and partly based on the cost of living in a location. Johnson said the changes are meant to give long-term TDY travelers an incentive to seek out extended-stay lodgings, which generally are less expensive.
Bilirubin is a yellow pigment that causes jaundice and dark yellow colored urine when present in increased amounts. Some people normally have higher bilirubin in their blood. This is known as Gilbert's disease. So their urine will naturally have more bilirubin.
The consistency of the urine may also change and it may have a murky appearance, the causes of which are discussed further under cloudy urine. A brown discoloration of the urine may be due to metabolites or colorants within certain foods, beverages, drugs or supplements. A common pathological cause is hematuria (blood in the urine) and though it is expected to stain the urine pink or red, in many cases of hematuria the urine appears light to dark brown.
