Per GURPS Powers, I would take this as giving a +2 bonus to Diagnosis, as doing what fine-quality mundane equipment would do. It rather seems to me that a vampire might have a sensitivity to blood composition exceeding that of a routine lab test. But I suppose if you're not giving any bonus, the comparison to an Accessory is fair.
