Backed by our vast industry experience, we are able to manufacture and export a complete range of fine quality â 300-19 EIA-total IgE from Saint Petersburg, Sankt-Peterburg, Russia. Normally IgE concentration in serum is very low. It increases gradually from birth to teen-age. In adults normal concentration of IgE may reach 100 IU/ml. In elderly people IgE level sometimes decreases.
IgE production is essential in anti-helminthic immunity. 15-20-fold increase in IgE concenÂtration (up to 1500 â 2000 IU/ml) is observed in the case of ascariasis.
