Your Rapid Test Development Challenges, Solved.

Infectious Disease

Rapid response is critical, but sensitivity often suffers. Our antibodies and antigens for COVID-19, HIV, Influenza, Malaria, and more enable accurate point-of-care diagnostics when time matters most.

Reproductive Hormones

Variability in fertility and pregnancy tests can impact trust. Our optimized hCG, LH, FSH, and Alpha-subunit reagents provide sharp lines and reproducibility for confident results.

Control Reagents

Batch variability can compromise QC. Our standardized positive and negative controls simplify validation and maintain consistency across production runs.aaaaaaaaaaaaaaaa

Colloidal Gold

Signal instability and poor line clarity slow development. Our ready-to-use conjugates and custom labeling options deliver vibrant lines and scalable performance for high-volume LFA manufacturing.

Tumor Markers

Cancer biomarker tests demand precision. Our validated CA125, CEA, AFP, and PSA antibodies and antigens support dependable detection in rapid test formats.

Serum Protein Markers

Cardiac, inflammation, and anemia tests require speed and accuracy. Our CRP, Troponin, and Hemoglobin reagents are fine-tuned for high specificity and rapid turnaround.

Drugs of Abuse

False positives and detection limits can derail screening accuracy. Our antibodies and antigens for cocaine, opioids, THC, and amphetamines ensure dependable results—even in complex samples.

Hematological Markers

Our hematological markers support rapid, point-of-care assessment of anemia and long-term glycemic control through precise detection of hemoglobin and hemoglobin A1.
