Active B12 (holotranscobalamin) ELISA (BIOHIT)

Product code: 602290 (96 wells)

Direct active vitamin D screening for suspected deficiency

The BIOHIT Active B12 (holotranscobalamin) ELISA directly measures holotranscobalamin (holoTC) – the biochemically active form of vitamin B12 – from human serum. This test is well-suited for the screening of patients with a suspected vitamin B12 deficiency, and overcomes the problems associated with traditional testing methods that measure total, rather than just active, vitamin B12 concentration.

Key Advantages

Simple technology ideal for any laboratory
Suitable for both automated and manual methods
Avoids interference from Intrinsic Factor Blocking Antibody (IFBA), unlike total B12 kits
Effective for resolving inconclusive total vitamin B12 values
