Why is a qualitative test performed before a semi-quantitative test? Why is it necessary to rotate the slide/card?What is the difference between cost per billable test and cost per reportable result. (Give examples referring from the laboratory environment)
- What level of RF in serum is clinically significant? Why is a 1:20 dilution of patient serum, rather than undiluted patient serum, used for the qualitative test? Describe how the RF concentration is computed?Can a urine specimen be run without proper labeling?How are clinical chemistry test results used to confirm or rule out a presumptive diagnosis? Why is this important and give references.
- make the test principle, materials required for the analysis, sample preparation, test procedure, indication of a positive result, complications/interferences, for nitrous acid test.Do you think standard plate counts are very accurate? Why or why not? When doing serial dilutions, why is it necessary to plate more than one dilution? You left a carton of orange juice on your counter for 3 days. When you taste it, it is very bubbly (as though it was carbonated), and it tastes more bitter than usual. (Note: acids taste bitter). What do you think could have happened? (Note: you can’t just say that bacteria grew—you must explain how the growth of the bacteria resulted in the changes in the orange juice.) Based on what you now know about the presence of bacteria on chicken and beef, why is it a good idea to use separate chopping boards for meat and for vegetables? Please help me thank youA nurse reconstituted a vial of 750 mg Cefuroxime Sodium Powder for Injection with 6mL of sterile water for injection. The reconstituted solution was dark amber-colored solution. The package insert states that solution colors range from clear to yellow depending on concentration, diluent, and storage conditions. The nurse was then hesitant to give the patient the solution due to its unusual dark color. Five portions were taken from a batch of cefuroxime sodium. Prior to testing in the instrument, each part was subjected to one of the following conditions: Conditions Specifications Temperature Portion 1: 8°C ± 2°C Portion 2: 30°C ± 2°C Portion 3: 40°C ± 2°C Light Portion 4: Kept in the dark Portion 5: Exposed to direct sunlight 1. Which form of the product – the powder for injection, the reconstituted product, or both – will you subject to the following conditions? Why do you think these forms can best address the problem?
- A sample is diluted by a factor of 10 five times. The 10^-3 dilution has 272 colonies on it. Assuming you plated the same volume on each plate, how many colonies would you expect to find on the 10^-4 plate? Include units and use OCD formula.Discuss the correct laboratory technique in using the centrifuge for qualitative analysis. Give two tips on its proper use.
