VeriGoldTM 维生素D
The VeriGoldTM Vitamin D Rapid Test is a chromatographic immunoassay intended for the in-vitro quantitative measurement of 25-hydroxyvitamin D concentration in human serum or plasma. As a widely recognized indicator of vitamin D status, this test is mainly used to support the clinical assessment of conditions associated with vitamin D deficiency, including rickets in children, osteomalacia and osteoporosis in adults, as well as secondary hyperparathyroidism.
Quantitative results enable monitoring of vitamin D supplementation therapy and support assessment of vitamin D status, including sufficient, insufficient, or deficient levels. With results available in minutes from serum or plasma, the 25-OH Vitamin D rapid test supports timely clinical evaluation in endocrinology, geriatrics, pediatrics, and primary care settings.

| Sample Types | Serum, plasma, whole blood, and fingertip blood |
| Sample Volume | Plasma or serum: 10 µL Whole blood: 15 µL |
| Collection Method | Capillary (fingerstick) or venous blood |
| Sample Stability | Stable for testing within 1 hour at room temperature (as validated) |
| Acceptable Anticoagulants | EDTA / Heparin / Citrate (as applicable) |
| Notes on Handling | Specimens should be collected and handled using standard laboratory procedures. Use fresh samples when possible and avoid hemolyzed, lipemic, or contaminated specimens. |
| Detection Method | Immunochromatography |
| Antibody Format | Monoclonal / sandwich |
| Signal Generation | Colloidal gold |
| Reading Method | Instrument-based |
| Mechanism | The assay is based on a chromatographic immunoassay principle, in which 25-hydroxyvitamin D present in the sample reacts with specific labeled binding reagents during migration along the membrane by capillary action. The resulting immune complexes are captured at the test region, generating a signal proportional to the concentration of 25-OH vitamin D in the specimen. |
