Entamoeba histolytica Antibody, Serum
Use
Entamoeba histolytica Antibody, Serum test is used primarily to assist in the diagnosis of extraintestinal, invasive amebiasis. Amebiasis is an infection caused by the protozoan parasite, Entamoeba histolytica, often leading to liver and lung abscesses due to invasive disease. This serological test can help support the diagnosis of such conditions, particularly amebic liver abscess, as the serology is known to play a crucial role in providing evidence of invasive disease associated with E. histolytica infection.
Special Instructions
Not provided.
Limitations
This serological test is not recommended for identifying or diagnosing acute intestinal amebiasis or noninvasive disease due to its poor sensitivity in these cases. False positives may occur due to previous episodes of intestinal amebiasis resulting in a positive serology. Moreover, serological results should only be used as an aid and not be interpreted as definitive diagnostic evidence on their own.
