Product Introduction

The fluorecare® VB12 Test Kit (Vitamin B12) developed by Microprofit is a quantitative immunofluorescence assay (FIA) designed for the accurate detection of vitamin B12 levels in human serum and plasma. As part of the fluorecare® POCT diagnostic platform, this test kit enables rapid and reliable quantitative analysis, supporting efficient clinical decision-making in laboratories, hospitals, and point-of-care testing environments.

Detection Principle

The fluorecare® VB12 test kit utilizes fluorescence immunochromatographic assay technology. Vitamin B12 in the sample reacts with fluorescent-labeled binding proteins, and the resulting signal is captured on the test line. The fluorescence signal is detected and analyzed by the fluorecare® immunofluorescence analyzer, enabling accurate and quantitative measurement of vitamin B12 concentration.

Clinical Applications

• Diagnosis of vitamin B12 deficiency

• Investigation of macrocytic and megaloblastic anemia

• Evaluation of peripheral neuropathy and neurological symptoms

• Nutritional status monitoring in at-risk groups (elderly, vegetarians, malabsorption)

• Clinical laboratory and decentralized POCT testing
