Urinalysis: Kidney and Urine Observations Data
What is the purpose of this exercise? Are there any safety concerns associated with this exercise? If so, list what they are and what precautions should be taken.
1. Safety precaution while handle specimen is important.
2. Wear appropriate precaution while handling specimen such as gloves, apron, and goggles.
3. Making sure label each test strips result to prevent confusion.
4. Good hand washing technique.
Exercise 1: Physical and Chemical Analysis of Urine
Observations
Data Table 1
Characteristic
Results/Remarks/Values
Color yellow
Clarity clear with no sediments
Odor none
pH 5.8
Glucose none
Protein none Questions
A. What is the normal pH range of urine? The normal values range from pH 4.6 to pH 8.0.
B. What substances in the urine might indicate that a person has diabetes?
High glucose (sugar) level will be present in the urine. When high glucose is present in the urinalysis test the person has diabetes. Extended lab testing is required to determine whether the results are accurate.
C. What factors might affect the color, odor and pH of a urine sample?
Factors that might affect the color, odor and pH of a urine sample include diet, medicines and certain diseases. Other factors might be kidney stones and fluid balance.
D. What are the three physiological processes involved in urine production?
The 3 physiological steps are glomerular filtration, selective re-absorption, and tubular secretion. The glomerular filtration occurs in the glomerulus under hydrostatic pressure and is a passive form of filtration. It removes all the high molecular weight materials. Selective re-absorption occurs in the Loop of Henle. It is an active process in which ions and other essential materials are reabsorbed. Tubular secretion occurs in the collecting tubule and it involves secretion
