Serotonin uptake characteristics in platelets of control subjects and patients with fibromyalgia

Variable

Controls (n = 38)

Patients with FM (n = 40)

V_max (pmol/10⁹ platelets per minute)

114 ± 6

90 ± 4^a

K_m (nM)

114 ± 15

96 ± 15

Results are shown as means ± SEM. FM, fibromyalgia; K_m, Michaelis constant; V_max, maximal uptake rate of specific serotonin transporter. ^ap < 0.001.
