URINALYSIS:  WORKSHEET


     The primary objectives of this worksheet are to report and explain the results of the urinalysis laboratory.
 

1. Analysis of your own urine sample:

     a. What was the pH of your urine?
 
 

     b. What was the specific gravity of your urine at the beginning of class?
          (Indicate if you were dehydrated or maximally hydrated before class.)
 
 
 
 

     c. What abnormalities (if any) did you observe in your urine sample?
 
 
 
 

2. Analysis of an unknown urine sample:

     a. Which unknown did you test?
 
 

     b. What abnormalities (if any) did you observe in the unknown sample?
 
 
 
 

3. Complete the following table, comparing the average specific gravities and
     urine volumes from each of the five treatment groups.
 
 

Group Treatment Average Specific Gravity Average Urine 
Volume (ml)
Initial  1 Hour 2 Hour 1 Hour 2 Hour
A Control          
B Hydrated          
C Isotonic          
D Dehydrated          
E Maximally 
Hydrated
         

 

4. Select one group which was different from control and briefly explain the mechanism
     by which the urine solute concentration was altered.
