Acid/Base Balance
Condition that occurs when the net rate at which the body produces acids or bases is equal to the net rate at which acids or bases are excreted
Amorphous
(adj.) shapeless, without definite form; of no particular type or character; without organization, unity, or cohesion
Bilirubin
an orange-yellow pigment in the bile that forms as a product of hemoglobin
Bilirubinuria
the presence of bilirubin in the urine
Casts
tubular structures found in urine composed mainly of mucoprotein secreted by certain cells of the kidney
Chain of custody
Special strict protocol for forensic specimens that requires detailed documentation tracking the specimen from the time it is collected until the results are reported.
Carcadian Rhythm
sequence of body changes every 24 hours
Creatinine
waste product of muscle metabolism, filtered out of the blood by the kidneys and excreted in urine
Critical Values
test results that indicate a potentially life threatening or greatly debilitating situation that must be reported to the provider immediately
Crystals
Found in normal urine sediment having no particular significance; should be noted because they may indicate disease states.
Culture and sensitivity
a laboratory test in which a sample is removed from an infection and placed in a culture medium in order to identify the type(s) of bacteria and then determine its sensitivity to a variety of antibiotics
Cultures
Microorganisms cultivated in a nutrient medium. Taken for testing.
Glucose
the form of sugar that circulates in the blood and provides the major source of energy for body tissues. When its level is low, we feel hunger.
Glucosuria
Presence of glucose in the urine
Hematuria
Presence of blood in the urine
Hyaline
Transparent clear. hyaline casts consists of mucuprotein. they are transparent and difficult to see in the urine.
Ketoacidosis
Accumulation of ketones in the body; occuring primarily as a complication of diabetes mellitus; if left untreated, it cause coma
Ketone
Chemical compound produced during an increased metabolism of fat; also, tesy on a reagent strip.
Ketonuria
Having ketones in the urine
Ketosis
A condition of the body burning fatty acids for energy in the absense of the appropriate glucose/carbohydrates. May be referred to as lipolysis
Leukocyte Esterase
Test on a reagent strip that indicates the presence ofwhite blood cells in the urinary tract.
Midstream Collection
Urine sample collected in the middle of a flow of urine
pH
scale that indicates the relative alkalinity or acidity of a solution; measurement of hydrogen ion concentration
Quality Control (QC)
procedures are designed to ensure accuracy and precision of laboratory tests and to discover and eliminate human error. calibration of machines
Reagent
chemical substances that detects or synthesizes other substances in a chemical reaction
Reagent Test Strip
narrow strip of plastic on which pads containing reagents are attached
Refractometer
an instrument used to measure the refractive index of urine which is an indirect measurement of the specific gravity of urine
Sediment
Insoluble materials that settles to the bottom of a liquid; material examined in the urinalysis microscopic examination
Specific Gravity
the ratio of the weight of a given volume of solution to the weight of the same volume of distilled water at the same temp test often performed during the urinalysis physical exam and can appear the reagent test strip
Supernatant
urine that appears to be above the sediment when centrifuged; poured off before sediment is examined under the microscope
Turbid
Opaque, not clear. used to describe urine that is cloudy.
Urea
Principle end product of protein metabolism
Urinalysis
the physical chemical and microscopic examination of urine and its components
Urinary Tract Infection (UTI)
The most common of all bacterial infections
Urobilinogen
colorless compound produced in the intestine after the breakdown by bacteria of bilirubin
