Interferon (IFN) is divided into two types. Type I interfering cords include α-IFN and β-IFN are produced by leukocytes and fibroblasts. Type II interferons, also known as γ-IFN or immunointerferons are mitotic. The original stimulated T lymphocyte production. Interferon is a highly effective antiviral biologically active substance and a lymphokine with extensive immunomodulatory effects. There are many methods for detecting interferon, such as plaque reduction method, virus quantification method, radioimmunoassay method and cytopathic inhibition method.

Basic Information

Specialist classification: Oncology examination classification: immune examination

Applicable gender: whether men and women apply fasting: not fasting

Tips: If there is fever or chill during the examination, you should inform the doctor immediately. Normal value

Cell micro-inhibition method 2 ~ 6KU / L.

Clinical significance

Reduce chronic bronchial asthma.


Requirements for inspection:

If there is fever or chill during the examination, you should inform the doctor immediately.

Note before inspection:

Follow the doctor's instructions to stop taking certain drugs that affect the metabolism of interferon.

Inspection process

With the development of monoclonal antibody research, some reliable quantitative methods such as radioimmunoassay and ELISA have been established. However, the disadvantages of such methods are low stability, specificity and sensitivity. Time-resolved immunoassay technology has the advantages of high sensitivity, long shelf life of the kit, easy operation, and non-radioactivity.

Not suitable for the crowd

Not suitable for people:

Patients who took certain drugs that interfere with the metabolism of interferon.

Adverse reactions and risks

There are no related complications and hazards.
