Echinococcus Granulosus IgG ELISA Kit
INTENDED USE
Human Echinococcus granulosus IgG ELISA kit is intended for measuring in-vitro quantitative concentrations of human IgG antibodies to Echinococcus granulosus (Echinococcus IgG) using serum or plasma samples. This assay has a minimum analytical sensitivity limit of 1.1 U/ml.
BACKGROUND
Echinococcus granulosus can also be called by many other names which includes hyper tape-worm, dog tapeworm or hydatid worm. It has the ability to infect many domestic and wild mammals in order to act as intermediate host for example humans, cats, sheep, horses, cattle, pigs, goats, kangaroos, camelids and deer. E. granulosus is found to be present around the world but the prevalence seems to vary considerably. It is often more abundant in rural areas which have livestock and wildlife in combination with poor sanitary conditions. Adult Echinococcus granulosus worms tend to be quite small (approx. 7mm), having only 4 segments where the final one is the largest and gravid (filled with eggs), the head (called scolex) consists of 4 suckers and there are a number of hooks which are useful for attaching to the gut wall.
ECHINOCOCCUS GRANULOSUS IGG ELISA KIT CONTENT

SENSITIVITY
The minimum detection sensitivity level of IgG antibodies to Echinococcus granulosus (Echinococcus-IgG) using current human Echinococcus IgG ELISA kit was 1.1 U/ml. The dynamic range for this assay is 1.0 – 200.0 U/ml.
