    LabCorp lowers Serotonin upper limit from 321 ng/mL to 207 ng/mL

    LabCorp lowered the upper limit for blood serotonin, which I find surprising, knowing the trend is to make the ranges bigger. Proof of the change from a recent test: @haidut is this a rare case of a lab like LabCorp lowering the upper limit for one of the harmful hormones by so much?
