This method of data reporting and the large sampling size he used gave credibility to his data. He also had the foresight to ...

Full blood count

... and types of different cells within the blood. The machine prints out, and/or sends to a computer, the results. Blood counting machines work by sampling blood, and sucking a standard amount through narrow tubing. Within this tubing, there are sensors that count the number of cells going through it, ...
