DIAGNOSTIC Flashcards
Provides important clinical information about kidney function and helps diagnose diseases
Urinalysis
Components of urinalysis
-Urine color
-Urine clarity and odor
- Urine pH and specific gravity
- Tests to detect protein, glucose, and ketone bodies in urine
-Microscopic examination of urine sediment after centrifugation to detect RBCs, WBCs, Casts, Crystals, and Bacteria
-Obtain via Mid-strem clean catch
Determines whether bacteria are present, as well as their stains and concentration
Urine culture
Includes the identification of the antimicrobial therapy that is best suited for a particular stain
Sensitivity
Assess the status of kidney function and Evaluate the severity of kidney disease
Renal function tests
What are the test for renal functions tests?
-Renal concentration tests
-Creatinine clearance
-Serum creatinine
-Blood urea nitrogen (BUN)
An expression of the degree of concentration of the urine that measures the density of a solution tot he density of water
Specific Gravity
Measures the number of solute particles in a kilogram of water
Urine osmolality
The end product of muscle energy metabolism
Creatinine
This test measures effectiveness of renal function
Creatinine
The nitrogenous end product of protein metabolism
Urea
Serves as an index of renal function
Blood Urea Nitrogen (BUN)
Normal creatinine level
0.6-1.2 mg/dl
Normal BUN Level
7-18 mg/dl
Detects and evaluates progression of kidney disease
Creatinine clearance
Creatinine clearance method of collection
24-hour urine specimen
The test measures volume of blood cleared of endogenous creatinine in 1 minute- approximate GFR
Creatinine clearance
