changes in unpreserved urine Flashcards
Oxidation or reduction of metabolites
Darkened Color
Bacterial growth and precipitation of amorphous material
Decreased Clarity (Turbid)
Bacterial multiplication causing urea to ammonia
Increased ammonia Odor
Urease-producing bacteria/loss of CO2 causing breakdown of urea to ammonia
pH Increased (Normal: less than 7)
Glycolysis and bacterial use
Decreased Glucose
Volatilization and bacterial metabolism
Decreased Ketones
Exposure to light/photo oxidation to biliverdin
Decreased Bilirubin
Oxidation to urobilin
Decreased Urobilinogen
Multiplication of nitrate-reducing bacteria
Increased Nitrite
Disintegration/lysis in dilute alkaline urine
Decreased RBC, WBC, casts
Multiplication
Increased Bacteria
Loss of motility, death
Decreased Trichomonas
