Toxoplasma gondii by Immunohistochemistry

Also known as: TOXOPL IHC

Clinical Use

Use

The Toxoplasma gondii by Immunohistochemistry test is used for the detection of Toxoplasma gondii in tissue or cell specimens. It utilizes immunohistochemistry staining techniques to identify the presence of the parasite in formalin-fixed, paraffin-embedded samples. The test is suitable for aiding in the diagnosis of toxoplasmosis, particularly in patients with clinical indications of the infection. The immunohistochemistry method provides a means to visually confirm the presence of T. gondii in suspect tissue samples, which can be crucial for accurate diagnosis and subsequent treatment decisions.
