Discuss the following: Whether the alternative testing method was made before or after the urine reagent strip Summarized Procedure Causes for False Positives Causes for False NegativesExplain the clinical significance and its normal and abnormal interpretation that could be associated with each reagent on the urine test strip .After a urine culture, 95 colonies are counted on a plate inoculated with 1 uL of urine samplpe. What is the CFU/mL of urine? How do I do this?
- Using 25 uL of a patient's serum, how much diluent would be needed to create a 1:2 dilution? ______ ulThe first step of a urinalysis procedure, before testing with a reagent stick, is to visually examine the urine for color, clarity and odor. These properties should be considered in addition to a patient’s clinical presentation, fluid intake and urine output. In the case of Sample B, the patient has presented with an overall healthy appearance. The quantity of urine is normal, the clarity of the urine is clear, but the color of the urine is tinged red, the odor is strong, and the patient is alarmed. From the following, select ALL questions which the patient should be asked, to help determine the cause of the color and odor changes. a. menstruation should be ruled out in females b. consumption of beets c. consumption of asparagus d. consumption of strawberriesFor a simple routine qualitative analysis, why is an early morning sample of urine used for the tests, and not a sample collected after a meal? Explain briefly.
- Determination of Creatinine in Serum and Urine Experiment; Question: Why are using this materials/chemicals in this experiment? *10% sodium tungstate *0.75 M NaOH Creatinine depot standard *0.67 N H2SO4 *Picric acid (0.04 M) Procedure: 3 mL of water, 1 mL of 10% sodium tungstate, 2 mL of 0.67 N H2SO4 are added onto the serum (2 mL), mixed well, and filtered after 5-10 minutes (protein-free serum filtrate). 3 mL of this filtrate is used for the test.All tubes are mixed, incubated at room temperature for 20 minutes and read against the reagent blank at 520 nm.First, the serum volume in the test tube is calculated.Since working with 3 mL standard, the absorbance of the standard tube belongs to 30 µg creatinine.Which is not a Limit test in the Sodium Chloride drug substance/raw material monograph? (Note: NaCl is used as a drug to counter hypotension (low blood pressure), and as a raw material in saline solution.)Differentiate the proper handling and specimen collection of urine sample for drug testing versus in routine urinalysis? (Subject: Clinical Chemistry 2)
