Where diagnosis saves lives

Advanced Medical Diagnostics for every setting

We supply rapid immunoassay kits, fluorescence-based readers (FIA), and portable PCR systems—building end‑to‑end screening programs from asymptomatic population checks to treatment pathways.

Solutions

Early, accurate diagnosis shortens time‑to‑treatment, prevents spread, and optimizes care pathways. Below is how our portfolio maps to major disease classes.

🦠 Infectious Diseases

Infectious Diseases

Examples: SARS‑CoV‑2 Ag, HBsAg, HCV Ab, HIV‑1/2 Ab, Influenza A/B, RSV, TB Ag.

❤️ Cardiovascular

Cardiovascular

Examples: TnI, CK‑MB, Myoglobin, NT‑proBNP, D‑dimer, hs‑CRP.

🧬 Hormonal Disorders

Hormonal Disorders

Examples: TSH, Free T3/T4 (thyroid); LH/FSH (reproductive); hCG (pregnancy); Prolactin; Progesterone.

🌾 Allergy

Allergy

Examples: Total IgE and specific allergens such as pollen, dust‑mite, peanut, shellfish.

🧪 Rapid Immunoassay

Colloidal Gold Test Kits

Reliable, equipment‑free screening. Clear C/T lines, fast time‑to‑result, ideal for clinics and outreach programs.

Targets: HCV Ab, HBsAg, HIV 1/2, Influenza, COVID‑19 Ag, TnI, CRP, and more.

✨ FIA

Fluorescence Immunoassay

Reader‑based, high sensitivity & specificity. Barcode & QC workflows, printable reports, LIS‑ready.

Use cases: cardiac markers, hormones, infectious diseases, inflammation.

🧬 Portable PCR

Rapid PCR Platforms

Compact thermal cycling with real‑time detection. Accurate confirmation testing at the point of care.

Deployable in mobile labs and hospital wards.

Technology

From first‑line screening to advanced confirmation, our workflow integrates multiple validated diagnostic methods.

Screening workflow diagram

Population Screening

Screening using a lateral flow immunoassay based on colloidal gold nanoparticles or fluorescent nanoparticles allows fast detection in large groups.

Confirmatory PCR

If necessary, suspected cases can be confirmed using more advanced PCR methods, providing high sensitivity and specificity.

FIA & LFA Principles

  • Fluorescently labeled detection antibodies (FIA)
  • Colloidal gold nanoparticle–based colorimetric lines (LFA)
  • Both methods rely on immobilized capture lines to ensure specificity

PCR Principle

  • Cycles of denaturation → annealing → extension
  • Exponential amplification of target nucleic acids
  • Real‑time fluorescence monitoring for quantitative readout

Partners

We collaborate with leading manufacturers and healthcare institutions across Asia, Europe, and the Middle East.
