Transferrin Rapid Test Cassette (Feces)

Quick Overview

The Transferrin Rapid Test Cassette is a fast, reliable, lateral flow immunoassay designed for the qualitative detection of transferrin in human feces. It supports early detection of gastrointestinal bleeding, including colorectal cancer, delivering results in just 5 minutes.

Why Choose Transferrin Rapid Test?

  • Early Detection of GI Bleeding: Transferrin is more stable in feces than hemoglobin, providing an accurate marker for gastrointestinal disorders.
  • Fast & Convenient: Simple visual test with results in 5 minutes.
  • Professional Reliability: Designed for use in hospitals, clinics, and physician offices.
  • High Accuracy: Proven >99% reproducibility and 100% agreement with commercial tests.

How It Works

The test uses immunochromatography technology:

  1. Fecal sample is applied to the cassette.
  2. Transferrin binds to antibodies on the test strip.
  3. Colored line at “T” indicates positive; line at “C” confirms proper testing.

Interpretation:

  • Positive: Two lines (C + T) – transferrin ≥40 ng/mL.
  • Negative: Single control line (C) – transferrin <40 ng/mL.
  • Invalid: No control line (C) – repeat test.

Key Features

  • Rapid Results: Detect transferrin in 5 minutes.
  • High Sensitivity: Detects ≥40 ng/mL transferrin.
  • No Cross-Reactivity: Safe from interference by food, common biological substances, or animal transferrin.
  • Professional Use: Strictly for in vitro diagnostic applications.

Usage & Sample Handling

  • Collect 1-2 g or mL of feces in a clean container.
  • Test within 6 hours; refrigerate (2–8°C) up to 3 days or freeze for longer storage.
  • Thaw frozen samples completely before testing; avoid repeated freeze-thaw cycles.

Step-by-Step:

  1. Bring test and sample to room temperature.
  2. Apply 3 drops (≈100 μL) of specimen to the cassette.
  3. Wait 5 minutes and read results.

Storage & Stability

  • Store in sealed pouch at 4°C–30°C (40°F–86°F).
  • Use within 1 hour once opened.
  • Avoid prolonged heat and humidity to maintain accuracy.

Safety & Precautions

  • For professional use only.
  • Treat all specimens as potentially infectious.
  • Wear gloves, lab coat, and eye protection.
  • Do not use after expiration date.

Reliable Performance

  • Sensitivity: ≥40 ng/mL transferrin.
  • Accuracy: 100% agreement with reference rapid tests.
  • Reproducibility: Over 99% intra- and inter-lab agreement.
  • No Interference: Compatible with common biological substances.

Applications

  • Routine physical exams
  • Monitoring gastrointestinal bleeding
  • Screening for colorectal cancer
