Analysis of markers in urine samples

In urine, markers are analyzed along with their metabolites, which are integrated over a specific period. These substances provide comprehensive insights into various physiological processes and are crucial for areas such as immune response, bone health, and reproduction. They also allow for the determination of life-event phases, such as puberty, and offer valuable indications of the influence of environmental factors and social structures.

 

Examples of analyzed markers

* In urine, the specific marker as well as its non-specific metabolites are measured.

Examples of species studied

Methods for correcting urine concentration

To optimize the analysis, spot urine samples are corrected for concentration using creatinine or specific gravity. Both established methods are available.
