Vitamin B_<12> (B_<12>) absorption test using a whole body counter with plastic scintillators is a clinically useful method for the diagnosis of B_<12> malabsorption. As described in our previous paper, a 103 percent value measurement was made 35 min after the oral administration of radioactive B_<12>. To simplified the method we tried to get the 100 percent value without measurement of the patient after the B_<12> administration. The radioactive B_<12> material was counted at a distance of 6 cm from the bed. Each count was corrected by physique of the patient. The correction factor is [numerical formula] The B_<12> absorption rate estimated by the initial value described above was compared with that obtained by our usual method for each patient. The coefficient of correlation and % agreement were 0.98 and 98 percent, respectively. This method is simple and convenient as a routine test.
