Giardia Intestinalis Antigen LIS Code: Giardia Ag

What Is Giardia Intestinalis Antigen?

Giardia intestinalis antigen refers to a diagnostic test used to detect antigens from Giardia intestinalis, a protozoan parasite that infects the gastrointestinal tract. This test helps confirm the presence of Giardia infection, which can affect both humans and animals.

How the Giardia Antigen Test Works

The test is conducted using a stool sample, which is examined in a laboratory for the presence of Giardia-specific antigens. Unlike traditional microscopy, the antigen test offers improved sensitivity and faster results, making it a preferred method for detecting active infections.

Symptoms of Giardia Infection

Giardia infections are common worldwide and may cause a variety of gastrointestinal symptoms, including:

Persistent or watery diarrhoea

Abdominal cramps and bloating

Nausea and fatigue

Unexplained weight loss

Symptoms can appear a few days after exposure and may last for several weeks if untreated.

How Giardia Spreads

The parasite is often transmitted through:

Contaminated drinking water or food

Direct contact with infected individuals or animals

Poor hygiene and unsanitary environments

Due to the nature of transmission, Giardia is frequently associated with waterborne outbreaks and can affect individuals of all ages.
