Al-Saleh et al reported a score based on hematopoietic factors for evaluating a patient with newly diagnosed multiple myeloma. The authors are from the Mayo Clinic and Abdulaziz University of Health Sciences in Riyadh.
Parameters:
(1) hemoglobin in g/dL
(2) platelet count in 10^9/L
(3) MCV in femtoliters
