Abstract: In the recently published article of Gökçay Canpolat et al, “Diagnostic accuracy of parathyroid hormone levels in washout samples of suspicious parathyroid adenomas: A single-centre retrospective cohort study.1” It has been brought to authors' attention that there were no details of the PTH assay included under Methods section. Below are the missing details: Subjects were asked not to take dietary supplements containing biotin for 12 hours or more before fine needle aspiration. Immediately after ultrasound guided aspiration, the washout samples were prepared for parathyroid hormone (PTH) measurement by rinsing the needle contents into centrifuge tubes with one mL of saline. Samples with visible bloody contents were not assayed. The tubes were centrifuged, and PTH concentrations were measured in the supernatant. PTH concentrations were measured with a Beckman Coulter Unicel Dxh 800 analyzer and the Access intact PTH chemiluminescent immunoassay. The serum reference range for serum PTH was 14-72 pg/mL, but there are no currently established reference ranges for PTH concentrations in needle washout samples. The washout fluid samples with much higher PTH concentrations than the serum PTH concentrations were interpreted as positive results. The authors would like to apologise for this omission and convey the above additional information.
