- Would you expect the results from the MAC test to corroborate the results from the EMB test? Explain why or why not.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?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 you
- In this question, you need to discuss the results you obtained from the BSA standards to generate your standard curve. Are you confident in the absorbance values you measured from the BSA standards? Was there variability between your duplicates? Comment on the shape of your standard curve and note the highest absorbance you would consider for interpolating the concentration of an unknown sample.For 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?Create an illustrated step-by-step schematic diagram of the following Qualitative test for Baudouin Test Huble's Test
