Tetanus Toxoid IgG ELISA Kit

Full Name: Tetanus Toxoid IgG ELISA Kit
Reactivity: Human
Sample Type: Serum, Plasma
Sensitivity: 0.004 IU/ml

BACKGROUND

Tetanus toxoid is used in order to prevent tetanus (also called lockjaw). This is an equine bacterial disease caused as a result of Clostridium tetani. It is able to enter the body via an open wound, although the this infection can also occur when there is a deep puncture wound for example following a bite, burn, cut or even an ulcer, which in many cases be caused by a scratch on the skin or by a tiny prick.

Immunization against tetanus is recommended for all infants/children and adults after 6-8 weeks of age, the tetanus immunization comprises of 3 or 4 injections over a period of time. It is essential to adhere to the advised immunisation schedule to guarantee that your body produces the required antibodies to combat this disease.

INTENDED USE

Human tetanus toxoid IgG ELISA kit is designed for detecting in-vitro amounts of human IgG antibodies against tetanus toxoid (tetanus-IgG) using plasma and serum samples. This assay has a minimum analytical sensitivity limit of 0.004 IU/ml.
