Access Vitamin B12 | REF 33000
Beckman Coulter Access Vitamin B12 (REF 33000) reagent pack for quantitative determination of vitamin B12 in human serum and plasma using Access immunoassay systems.
The Beckman Coulter Access HIV Ag/Ab Combo reagent (REF C39450) is a paramagnetic particle, chemiluminescent immunoassay designed for use on Beckman Coulter Access family immunoassay analyzers. It enables the simultaneous qualitative detection of HIV-1 p24 antigen and antibodies to HIV-1 (groups M and O) and HIV-2 in human serum and plasma, supporting earlier detection of HIV infection compared with antibody-only assays.
The pack is supplied as a ready-to-use reagent cartridge format compatible with the closed Access reagent handling workflow, helping laboratories standardize HIV screening alongside other routine immunoassay testing on a single platform.
Key Features
Combined detection: Simultaneous qualitative detection of HIV-1 p24 antigen and anti-HIV-1/2 antibodies in a single test.
4th generation design: Targets both antigen and antibody markers to support narrowing of the diagnostic window period.
Chemiluminescent technology: Paramagnetic particle chemiluminescent immunoassay chemistry for sensitive signal detection.
Ready-to-use cartridges: Pre-filled reagent packs designed for direct loading onto the analyzer.
Platform compatibility: Formulated for Beckman Coulter Access family immunoassay systems.
Workflow consolidation: Allows HIV screening to be run alongside other Access immunoassays on the same instrument.
Clinical Applications
HIV screening: Qualitative screening of human serum and plasma samples for HIV-1 p24 antigen and antibodies to HIV-1/2.
Blood and donor program support: Use in laboratory testing programs where combined antigen/antibody HIV screening is required, in line with local regulations.
Infectious disease laboratories: Routine immunoassay testing in hospital, reference, and clinical diagnostic laboratories.
Diagnostic workup: Initial laboratory marker for suspected HIV exposure as part of a broader testing algorithm. Regulatory clearance and intended use vary by region; refer to the official Instructions for Use.
