Random Urine Collection for Urinalysis. Random urine samples are used for urinalysis, which can screen and diagnose metabolic disorders and urinary tract infections. Your doctor may order urinalysis to determine, for example, the cause of bloody urine, abdominal pains or burning sensations associated with urination.
1 Place potato slices into a large bowl of cold water as you slice. 2  Drain, and rinse, then refill the bowl with water, and add the salt. 3  Let the potatoes soak in the salty water for at least 30 minutes. 4  Drain, then rinse and drain again. 5  Heat oil in a deep-fryer to 365 degrees F (185 degrees C).
Pour oil into a large skillet over medium heat, filling it so the oil fills the pan a third of the way up. In a large bowl, combine potatoes, cheese, chives, hot sauce, salt, and egg. Fry the mashed potatoes, a few at a time (without crowding the pan), cooking each side until lightly golden, 2 to 3 minutes per side. Top potatoes with sour cream and additional chives before serving.
