5.3 Physical Examination of Urine Flashcards
Amorphous
without definite shape
Amorphous Phosphates
granular crystals without uniform shape that can form in alkaline urine, give urine sediment a whitish appearance after centrifugation, and appear clear microscopically
Hematuria
the presence of blood in the urine
Hemoglobinuria
the presence of hemoglobin in the urine
Ketones
a group of chemical substances produced during increased fat metabolism; ketone bodies
Maple Syrus Urine Disease
a rare metabolic condition in which the amino acids leucine, isoleucine, and valine are not metabolized, causing the urine to have the odor of maple syrup
Melanin
a dark pigment of skin, hair, and certain tumors
Amorpous Phosphates
granular crystals without uniform shape that can form in alkaline urine, give urine sediment a whitish appearance after centrifugation, and appear clear microscopically
Mucus
a substance secreted by cells lining the urethra and vagina and that can be present in urine
Myoglobin
a pigmented, oxygen-carrying protein found in muscle tissue
Opalescent
having a milky iridescence
Phenylketonuria
an inherited condition in which the amino acid phenylalanine is not metabolized, but is excreted into the urine and causes urine to have a mousy or musty odor
Porphyrins
a group of light-sensitive, pigmented, ringed chemical structures that are required for the synthesis of hemoglobin
Refractive Index
the ratio of the speed of light in air to the speed of light in a solution
Refractometer
an instrument for measuring the refractive index of a substance; also called a total solids meter
