Study reveals urinary metabolites effectively indicate mast cell activation in various conditions, suggesting better diagnosis tools.

This research aims to establish urinary metabolites as sensitive markers for mast cell activation compared to serum tryptase levels.
Collected urine and blood samples from healthy volunteers and patients with asthma, chronic urticaria, and mastocytosis.
Analyzed urinary excretion of 11β-PGF 2 α, tetranor-PGDM, and t-MIAA using specific methods.
Compared levels of urinary metabolites with serum tryptase measurements.
Patients with mastocytosis exhibited 1.5-30 fold increases in urinary mediator levels compared to healthy volunteers.
Some mastocytosis patients showed elevated serum tryptase, but this was not consistent across all patients.
No significant changes in urinary metabolites were observed in asthmatic patients.

Bood et al. (2014) studied this question.
