A Brief Description of the Operation of the DoD Serum Repository

Abstract

Beginning in 1985, the United States military has consistently maintained repositories of frozen human serum for force health protection reasons. The separate repositories created by the Army, Navy, and Air Force during the startup of their human immunodeficiency virus (HIV) screening programs were fully combined by 1996, along with the Defense Medical Surveillance System, to form the DoD Serum Repository (DoDSR). Currently comprised of 450,000 square feet of storage space at a constant -30 degrees Celsius, the DoDSR, operated by the Armed Forces Health Surveillance Center (AFHSC), receives approximately 2 million new serum specimens per year as a result of current HIV screening programs and pre- and post-deployment serum collection. Following initial testing for HIV when required, each specimen remains frozen until needed for clinical testing or a public health study, and its physical location is carefully tracked. Certain militarily-relevant research studies occur, though the serum from a specific individual is never allowed to be fully exhausted. AFHSC maintains careful control over the repository, utilizing a scientific review board to determine which requests for serum will be granted. As of 2012, only 0.42% of all of the frozen specimens in the DoDSR had been thawed for any type of use. The addition of new specimen processing capacity and significant changes to policy would be required if more of the specimens were to be used to answer relevant epidemiological, operational, or medical research questions.

Autoantibodies to Malondialdehyde–Acetaldehyde Are Detected Prior to Rheumatoid Arthritis Diagnosis and After Other Disease Specific Autoantibodies

“…Serum samples from the US Department of Defense Serum Repository (5) were obtained from RA patients prior to and after diagnosis. A screening was performed using the military’s electronic medical record for active‐duty personnel with ≥2 RA diagnostic codes (≥1 from a rheumatologist).…”

Live Oral Adenovirus Type 4 and Type 7 Vaccine Induces Durable Antibody Response

“…Paired serum from 60 subjects collected prior to vaccination (pre-vaccination) and three post vaccination samples up to 6 years (>30 days to one year, two to three years, and five to 6 years) after co-administering live oral AdV-4 and AdV-7 vaccine in 2011 were obtained from the Department of Defense Serum Repository (DoDSR), maintained by the Armed Forces Health Surveillance Branch (AFHSB), Department Health Agency (DHA) [11,12], for a total of 240 samples (Table S1). DoDSR serum samples are collected for operational and epidemiologic purposes as part of the Defense Medical Surveillance System (DMSS), a command-directive, public health surveillance practice; samples are accessible only to Department of Defense investigators [11,12].…”
