Typhi Dot IgG

Typhoid fever is a bacterial infection caused by Salmonella typhi. The Typhi Dot IgG Test identifies IgG antibodies produced by the immune system after exposure to the bacteria. IgG antibodies usually appear later in the infection or remain after recovery, helping doctors understand whether the infection is past, ongoing, or recurrent.

Uses of the Test

• Detect past or prolonged typhoid infection
