A photovoltaic module is a grouping of connected solar cells used to collect energy from solar radiation. Each cell is electrically connected into these modules, which in turn are merged into a panel. When photovoltaic panels are installed at various locations they become known as arrays.
Immunoglobulin E (IgE) is a type of antibody (or immunoglobulin (Ig) isotype) that has only been found in mammals. IgE is synthesised by plasma cells. Monomers of IgE consist of two heavy chains (Îµ chain) and two light chains, with the Îµ chain containing 4 Ig-like constant domains (CÎµ1-CÎµ4).
It measures the overall quantity of immunoglobulin E in the blood. It may be ordered by itself, before, or along with allergen-specific IgE tests, depending upon whether or not a person or healthcare practitioner has identified potential substances to which the person may be allergic.
