Since then, DBS testing for decades has remained predominantly focused on the diagnosis of infectious diseases especially in resource-limited settings or the systematic screening of newborns for inherited metabolic disorders and only recently have a variety of new and innovative DBS applications begun to emerge. For many years, pre-analytical variables were only inappropriately considered in the field of DBS testing and even today, with the exception of newborn screening, the entire pre-analytical phase, which comprises the preparation and processing of DBS for their final analysis has not been standardized. Given this background, a comprehensive step-by-step protocol, which covers al the essential phases, is proposed, i.e., collection of blood; preparation of blood spots; drying of blood spots; storage and transportation of DBS; elution of DBS, and finally analyses of DBS eluates. The effectiveness of this protocol was first evaluated with 1,762 coupled serum/DBS pairs for detecting markers of hepatitis B virus, hepatitis C virus, and human immunodeficiency virus infections on an automated analytical platform. In a second step, the protocol was utilized during a pilot study, which was conducted on active drug users in the German cities of Berlin and Essen.","is_dataset_classified":null,"base_score":3.7376696182833684,"endowment":3.7376696182833684,"datacite_reuse_total":0,"file_count":0,"downloads":0,"views":0,"has_version_chain":false,"is_dataset":false,"is_oa":false,"pmid":"21097893","pmcid":null,"openalex_id":"https://openalex.org/W4206063734","authors":[],"funders":[],"total_grants":0,"fwci":0.7954,"citation_percentile":0.75477842,"influential_citations":0,"citation_trend":[{"year":2017,"count":1},{"year":2018,"count":3},{"year":2019,"count":2},{"year":2020,"count":2},{"year":2021,"count":4},{"year":2022,"count":3},{"year":2023,"count":9},{"year":2024,"count":10},{"year":2025,"count":4},{"year":2026,"count":3}],"oa_status":"closed","license":null,"oa_locations":[{"url":"https://www.jove.com/v/52619/dried-blood-spots-preparing-processing-for-use-immunoassays-molecular","host_type":"publisher"},{"url":"https://doi.org/10.3791/52619-v","host_type":"journal"}],"fields_of_study":["Blood groups and transfusion","Biosensors and Analytical Detection","HIV Research and Treatment"],"mesh_terms":[],"keywords":["Dried blood","Dried blood spot","Human immunodeficiency virus (HIV)","Protocol (science)","Medicine","Spots","Blood collection","Limited resources","Computer science","Virology","Pathology","Medical emergency","Chromatography","Chemistry"],"sdg_mappings":[],"linked_datasets":[],"clinical_trials":[],"software_tools":[],"database_accessions":[],"source":"live","citation_network_status":"fetched"},"created_at":"2026-07-30T02:58:05.994295Z","pmid":null,"pmcid":null,"fwci":null,"citation_percentile":null,"influential_citations":0,"oa_status":null,"license":null,"views":0,"total_file_size_bytes":0,"version_count":0,"fair_f":null,"fair_a":null,"fair_i":null,"fair_r":null,"fair_zscore":null,"fair_rationale":null,"fair_model":null,"fair_agent_version":null,"fair_fulltext_source":null,"fair_has_llm":null,"fair_computed_at":null,"clinical_trials":[],"software_tools":[],"db_accessions":[],"linked_datasets":[],"topics":[]}
