To the Editor: Belfort et al. (Jan. 23 issue)¹ define the HELLP syndrome as hemolysis, elevated liver enzymes, and a platelet count below 150,000 per cubic millimeter. As the person who established the criteria for the diagnosis and named the entity the "HELLP syndrome," I would appreciate the authors' use of the correct platelet count, as described in my original report² and as cited in the reference they provide³: it is 100,000 platelets per cubic millimeter.
