FOB Transferrin Combo Rapid Test kit 2 in 1

The FOB Transferrin Combo Rapid Test Kit (2 in 1) is a fast, reliable immunochromatographic assay designed for the qualitative detection of human hemoglobin (FOB) and transferrin in fecal samples. By combining two important gastrointestinal bleeding markers in a single test, it provides a more comprehensive preliminary screening for occult blood in the gastrointestinal tract.

This easy-to-use kit is intended for self-testing at home by lay users, offering clear results within 15 minutes. The dual-marker approach helps improve detection sensitivity, as transferrin is more stable in the digestive tract than hemoglobin, making the test especially useful for early screening of potential gastrointestinal disorders.

Key Features:

• 2-in-1 detection of fecal occult blood and transferrin
• Rapid results within 15 minutes
• Simple, user-friendly home self-test
• Qualitative screening for gastrointestinal bleeding
• In vitro diagnostic use only

What is a transferrin blood test for?

A transferrin test is a protein measurement used in clinical practice to help diagnose and evaluate a variety of acute and chronic diseases. It is commonly performed using methods such as immunoturbidimetry, enzyme immunoassay (ELISA), immunodiffusion, and radioimmunoassay. Because it provides relatively precise and reliable data, the transferrin test has high clinical reference value.

Detailed explanation of the transferrin test

1. Clinical significance
Transferrin is an important protein in the human body that transports iron. Clinically, it is mainly used as a key indicator to assess the body’s iron storage and iron-binding capacity. In addition, transferrin may also serve as a marker for certain tumors.

2. Normal reference range

• In healthy adults, transferrin levels are typically 2.20–4.0 g/L when measured by enzyme immunoassay.

• When measured by immunoturbidimetric methods, the reference range is approximately 28.6–51.9 µmol/L.
  (Reference values may vary depending on the testing method and laboratory.)

3. Interpretation of elevated transferrin levels
If transferrin levels remain above the normal range for a long time or rise sharply, this may suggest pathological changes. Common associated conditions include:

• Iron deficiency anemia

• Hepatocellular necrosis

• Acute viral hepatitis

4. Interpretation of decreased transferrin levels
A significant reduction in transferrin levels may indicate different diseases depending on the pattern:

• Sudden decrease: may suggest infectious diseases, hemochromatosis, or epidemic hemorrhagic fever

• Persistently low levels: may be associated with chronic hemolytic anemia, primary liver cancer, or aplastic anemia

5. Factors affecting test results
Several factors can interfere with transferrin test results, including:

• Pregnancy

• Age

• Oral contraceptives

• Sex hormone use

As people age, transferrin levels tend to decrease gradually and may be slightly lower than in young or middle-aged adults. In contrast, pregnant individuals or those who have recently used sex hormones or oral contraceptives may show significantly elevated transferrin levels.
