Why oestrogen metabolites matter
Blood, urine and saliva are different sample matrices. A urine metabolite panel reports selected downstream oestrogen metabolites and ratios; it does not replace clinically indicated blood tests, history or examination.
2-OH, 4-OH and 16-OH metabolites are reported as measured values and relationships within the laboratory report. Their meaning depends on the assay, reference information and clinical context.
The report does not on its own quantify cancer risk, establish a diagnosis or determine whether hormone treatment is appropriate.
