Objective To probe how to accurately number the white cells quickly with the help of half-auto blood analy- sing machine to get the blood of the nerve end when the temperature outside is rather low in winter.Methods One method is diluting the sample,but not pre-heating it and puting it into the machine one minute later;another is pre-heating it and put it into the machine five minute later.The third is to use the hand numbering.Results The number of the white cells that were not pre-heated is more than those of the latter two,p0.05.The number of the white cells that is pre-heated and that from hand numbering are not different apparently,p0.05.Conclution The sample should be pre-heated to number the white cells of the blood of the nerve end when the temperature outside is rather low in winter.Moreover,too much time is unnecessa- ry and five minutes is enough for numbering the white cells.
