To the Editor The study on excretion of glyphosate in older adults1 was analyzed inappropriately. First, Table 1 reported levels above the limit of detection (LOD). To report quantifiable values, a limit of quantification (LOQ) is required. Only values greater than the LOQ are reliably quantifiable. Levels greater than the LOD and less than the LOQ can only be interpreted as “presence,” whereas levels less than the LOD can only be interpreted as “absence.”2
