Urine Analysis

Lab Objective

The objective of this experiment shall be to examine the effects of different types of fluids on the renal system including rate of urine production, pH, and specific gravity.

Hypothesis

The group drinking water will have the highest rate of urine production. The group that drinks water only when thirsty will have the lowest rate of urine production. The specific gravity of urine for all treatment groups will be around 1.000. The pH for all treatment groups will be around 6, which is slightly acidic.

Background and Information

Kidneys, without a doubt, are one of the human body’s most essential organs. Kidneys are crucial and necessary in order for the body to be able to maintain
The rate of urine production is measured in ml/min. The group who drank 7.5 ml of water had an average rate of urine production of 1.278 ml/min an hour before the lab. After drinking the 7.5 ml of water, the group had an average rate of urine production of 2.778 ml/min at thirty minutes. After sixty minutes, the average rate of urine production increased to 3.333 ml/min. At ninety minutes, the average rate of urine production decreased slightly to 2.889 ml/min.

The group who drank 16 ml of water had an average rate of urine production of 0.542 ml/min an hour before the lab. After drinking the 16 ml of water, the group had an average rate of urine production of 2.533 ml/min at thirty minutes. This was expected because these subjects drank a large amount of water based on their body weight. After sixty minutes, the average rate of urine production increased substantially to 10.4 ml/min. At ninety minutes, the average rate of urine production decreased slightly to 8.283
The group had an average rate of urine production of 1.10 ml/min at thirty minutes. After sixty minutes, the average rate of urine production slightly increased to 1.94 ml/min. At ninety minutes, the average rate of urine production slightly decreased to 1.66 ml/min.

The group who drank soda with caffeine had an average rate of urine production of 0.53 ml/min an hour before the lab. The group had an average rate of urine production of 1.89 ml/min at thirty minutes. After sixty minutes, the average rate of urine production remained the same. At ninety minutes, the average rate of urine production slightly increased to 2.11 ml/min.

The group who drank soda without caffeine had an average rate of urine production of 1.34 ml/min an hour before the lab. The group had an average rate of urine production of 1.59 ml/min at thirty minutes. After sixty minutes, the average rate of urine production increased to 3.46 ml/min. At ninety minutes, the average rate of urine production decreased to 1.92
