KNHANES Biobank

KNHANES Biobank provides access to biospecimens and genotyping data from the Korea National Health and Nutrition Examination Survey for public health research.

Key Features:

• Biospecimen Repository: The biobank provides serum, plasma, extracted DNA, and urine specimens collected from KNHANES participants.
• Genotyping Data: KoreanChip genotyping data comprising > 833,000 genetic markers for approximately 19,300 participants is available.
• Epidemiological Data Linkage: The biobank links biospecimens with vast epidemiological data from the KNHANES survey.
• Sample Scale: Biospecimens from a total of 95,455 participants have been deposited, with approximately 35,500 biospecimens available as of December 2024.

Scientific Applications:

• Public Health Research: The biobank supports research related to various public health concerns based on the general Korean population.
• Population Genetics: KoreanChip genotyping data enables genetic association studies and population-level genomic analysis.
• Health Policy Evidence: The linked survey and biospecimen data provide evidence for health policy and health interest statistics.

Methodology:

Blood samples are collected from people aged 10 years or older, and urine samples are collected from people aged 6 years or older during KNHANES health examinations. Genotyping is performed using the KoreanChip array. Researchers access resources through the HuBIS_Desk online platform with official project approval.
