Read full description

Please classify leukocytes up to the number of upper bounds while looking through the microscope in this application and count. It is not necessary to take one's eyes off the microscope because to which button it touched can be distinguished by the difference of the sound. The end sounds it if it counts to the upper bound. When the real number of the white blood corpuscle is input, the real number of various white blood corpuscles is calculated. The counted upper bound can be changed though sets to 100.
