One more cell counting question

... I am working on calculations for this same lab. The standard I started with was created from 10mL of culture plus 1mL of TCA, so it has a dilution factor of 1.1 I then created a diluted sample from this standard by removing 0.5mL from it, and adding 0.5mL of water to it. Should I take ...

Re: Oral Glucose Tolerance Test

... So you dilute the samples to reduce the amount of glucose in the assay to get better accuracy. You then have to adjust the assay value by the dilution factor to calculate the glucose level in the original, undiluted plasma sample. Say you diluted the sample by a factor of 10 (1 part plasma ...
