help answer all the answer with the solution thank you. 1. Given the following values, calculate the RPI: observed reticulocyte count=6.0%;Het = 0.30 L/L (which would give a maturation time of 2.0 days) 2. A manual white blood cell count was performed. A total of 36 cells were counted in all 9 "larger" squares of a Neubauer-ruled hemacytometer. A 1:10 dilution was used. What is the WBC? 3 3. In a reticulocyte count, 985 red cells and 15 reticulocytes were...
Question 4 2 pts You counted 200 cells in one "red" ("A", "big", 1 mm x 1 mm) square of a hemacytometer. The dilution factor is 1. What is the cell density of this culture? 2,000 cells/mL O 2x 10' cells/mL 2 x 106 cells/mL O200 cells/mL 2x 105 cells/mL Question 5 2 pts

Your sample will now be diluted to 1:2000 with an isotonic saline solution. Furthermore, when using a hemocytometer to count RBCs, only five squares of the central field are counted as indicated by the following diagram (Total # of cells counted)(10/# of 1 mm^2 fields counted)(dilution factor) = # of cells/ul by the following diagram: 400X 100X Figure 4: Pattern used for counting RBCs in the center field of a hemocytometer. Upon loading your diluted sample into the hemocytometer, these...
In an investigation into a patient’s red corpuscle count, the number of such corpuscles appearing in each of 400 cells of a haemocytometer was counted. The results were as follows: No. of red blood corpuscles 0 1 2 3 4 5 6 7 8 No. of cells 40 66 93 94 62 25 14 5 1 It is thought that a Poisson distribution with mean .. provides an appropriate model for this situation. (a) Estimate mu, the Poisson parameter. (b)...
Tommy, a medical laboratory scientist, participated in a humanitarian mission with other medical professionals to South America last summer. He received a peripheral blood specimen from a 20 years old lady complaining sore throat with a presumptive diagnosis of infectious mononucleosis. Using the Unopette manual system, he counted a total of 200 WBCs in 4 larger squares of the hemocytometer with a dilution factor of 20. He also performed 100 WBCs differential from the same tube. He found 20 nucleated...

Your colleague in the laboratory was able to collect all his raw data from a growth curve on the Hela S3 cell line, but had to leave unexpectedly and has asked you to perform cell calculations to show your professor. This what your colleague did: he seeded cells into a 24-well plate (allows for replicate sampling and it is much easier to handle one 24-well plate rather than 24 flasks), and on each of the days indicated in the table...
