Urine Analysis Lab Report

1. Cut four 6-inch pieces of dialysis tubing and soak in a coffee cup filled with tap water for 2 hours prior to your start

The dialysis tubing will be clamped at one end in order to fill it and then clamped at the other end to seal the filled bag. If the bag is not soft and floppy, the experiment will not work. Blot a bag with a paper towel to absorb the moisture and weigh it, if this blotting process is not done it could interfere with the weight readings creating inaccurate information. After the bags of the solutions are prepared, they will be placed into five different beakers with different solutions. Beakers 1-4 will be filled with tap water and the fifth beaker is filled with 40% sucrose and water. Fill each beaker with just enough water or solution so that the bag is covered and place the bags in the beakers simultaneously and record each time. Every 10 min the bags are to be taken out, blotted, and weighed again before returning them back into their respective beaker for another 10 min. The process is repeated until you have reached 90 min. The weights should be recorded in grams (g).

1) Apply the stain to your first unknown slide and examine it under the microscope.

After all results have been recorded, pour all of the solutions down the drain, rinse equipment and clean up the

2. Measure out 25 to 45 grams of one of the four metals on the trough. This may require several "clicks."

I would assess the amount of output she has in a time period and the specific gravity of the urine.

4.Measure 35mL of warm water and add them into each of the 4 test tubes at about roughly the same time. It is essential that the water is warm. Do not seal the test tube.

4. Take a piece of dialysis(as cut earlier), find the mass of the dialysis, and the zero out the scale on

XII. Take the 250 ml beaker to your lab bench. Set up a gravity filtration with a plastic funnel, folded wet filter paper, and an Erlenmeyer flask. Pour the content in the 250 ml beaker slowly through the filter paper. Wash the filter paper with deionized water. Dispose of the filtrate in the proper labeled waste container.

Allow 4 hours of urine flow before sending the culture to wash out the biofilm.

Dispense .5 mL water into the already weighed conical vial, replace cap and face insert on its down side.

Lab Urinalysis – Laboratory urinalysis services are performed for screening and intervention purposes. This is aimed at helping the patient withstand urges to use drugs. Such monitoring also can provide early evidence of drug use so that the individual’s treatment plan can be properly adjusted.

4. Prepare a vacuum filtration apparatus using a buchner funnel. Obtain one filter paper for each one of your samples, weigh them and record their mass in your notebook (label them with a pencil to be able to differentiate them later).

Perform a urinalysis when possible to find levels of Specific Gravity (how concentrated the urine is), pH, Protein, Blood, Nitrites, Leukocytes, Ketones, Glucose and Bilirubin. The results of this test can help identify any possible impairment in renal function and identify the presence of an infection (Vera, 2011).

1. Number four clean test tubes 1-4. 2. Place 1 ml (or 20 drops) of the following solutions into each tube: water, egg albumin, starch, and chicken broth. 3. Add 3 drops of Buiret reagent to each tube and gently shake
