What are the advantages of testing mycotoxins in urine?

According to Escrivá et al., (2017),

Urine is the body fluid most often used to measure mycotoxin exposure due to large amounts being easily and non-invasively collected, although blood (serum, plasma) has also been used. Hence, detection of mycotoxins in human or animal urine allows more accurate and objective exposure assessment at an individual level since it covers exposure from all sources, thus reducing uncertainties related to occurrence and consumption rates. On the other hand, urine analysis may provide widely valuable information, from mycotoxins toxicokinetics, ADME and bioavaliability studies, to human biomonitoring and exposure assessment. Urine analysis of mycotoxins can be used to establish population reference ranges and identify vulnerable consumer groups and individuals with higher exposures

Thus, being able to test the main elimination route for mycotoxins and their metabolites within a longer detection window, which can be used to quantify the exposure and correlate with patient symptoms, and being a non-invasive sampling method are advantages of testing via urine.
