her skin seems to be a great deal more itchy than several years ago, and that the episodes of itchiness are sometimes triggered by a hot
shower. Physical examination demonstrates hypertension, splenomegaly, and a ruddy complexion seen best in the face, palms, and nailbeds. The patient did not appear to be dehydrated.
The patient has an erythrocyte count of 6.7 million/mm3. Which of the following studies would be helpful in establishing that an absolute
increase in erythrocyte mass has occurred?
A. Free erythrocyte protoporphyrin
B. Hematocrit
C. Hemoglobin
D. Partial thromboplastin time
E. Radioactive chromium labeling
