A recent study set out to investigate the correlation between blood markers and pain intensity in women with fibromyalgia (FM). The researchers examined the correlation between proteins and pain intensity, sensitivity, and psychological distress among participants. Samples from 30 FM patients and 32 controls were used for analysis. The results showed that levels of plasma proteins involved in inflammatory, immunity, and metabolic processes were different between the FM and control group. These findings are significant for understanding the biological abnormalities in FM. However, more studies are needed until a blood test will be available to diagnose individuals with FM.
