A patient was administered 100kBq of I-131 RISA, a radio-iodinated serum albumin which remains in the bloodstream. A second 100kBq sample was diluted to 3000ml to create a standard solution. A 5 ml aliquot of this solution was analysed in a gamma counter and provided a count rate of 3050cpm. A 5ml sample of the patient's blood provided a count rate of1660 cpm. What is the patient's blood volume?

Answer 1

Answer #1

The volume of patient blood is inversely proportional to the cpm activity.

$Volume of Patient Blood3050 Volume of solutioin 1660$

$3050 Patient Blood Volume= (3000 ml) 1660 5512 ml$

Hence the patient's blood volume will be equal to 5512 ml
