Standard operating procedures for quality control of oral biospecimens at the Korea Oral Biobank Network

PURPOSE: The Korean Oral Biobank Network (KOBN) collects, stores, and provides oral samples for research. Quality control (QC) of biospecimens is necessary to ensure that they meet the basic prerequisites before being sent to researchers. This study presents the standard operating procedures (SOPs) for the QC of biospecimens. METHODS: QC methods using molecular genetic techniques according to sample types, including teeth, blood, oral soft tissue, oral tissue-derived cells, saliva, mouth rinse solution, dental plaque, and gingival crevicular fluid, are described in detail. RESULTS: The KOBN established SOP for oral biospecimen QC and assessment methods. CONCLUSIONS: To ensure a stable supply of high-quality biospecimens for researchers, regular QC checks should be carried out according to the SOP following the specifications of the Korea Biobank Network under the Korea Disease Control and Prevention Agency.
