Question

1) if 5 parts sample is added to 10 parts diluents, what is the dilution that was just made?

2. What is the ratio if 5 parts sample volume is added to 10 parts diluents volume?

3. In a 1 to 3 dilution, what is the dilution FACTOR?

4. In a 1 to 10 dilution, what is the dilution FACTOR?

5. What is the dilution FACTOR if 40 mcL of sample added to 260 mcL of diluent?

6. What is the dilution FACTOR if 100 mcL of sample is added to 0.900 mL of diluents?

7. If a sample was diluted so that the dilution FACTOR was 5 and had a diluted value of 50

mg/dL, what result is reported to the doctor?

8. A sample’s glucose concentration was above the highest standard’s value and so the sample

had to be diluted and reanalyzed. If 0.5 mL was added to 2.5 mL diluents and the reanalyzed

sample had a concentration of 115 mg/dL, what glucose value is reported to the physician?

9. A 1 to 25 dilution was performed on a sample to that was analyzed for ALT but had an initial

concentration higher than the highest standard. The diluted sample was reanalyzed and the

diluted sample’s result was 48 IU/L. What is the result that is reported to the physician?

10. A 10- fold serial dilution (each tube is a 1 to 10 dilution) was performed using 3 tubes. What

is the dilution FACTOR of the third tube?
