Additionally, some of these reagents consist of antisera conjugated with a fluorescent dye (immunofluorescent reagents) used to identify Toxoplasma gondii from clinical specimens. The identification aids in the diagnosis of toxoplasmosis caused by the parasitic protozoan Toxoplasma gondii and provides epidemiological information on this disease. Congenital toxoplasmosis is characterized by lesions of the central nervous system, which if undetected and untreated may lead to brain defects, blindness, and death of an unborn fetus. The disease is characterized in children by inflammation of the brain and spinal cord. ## Classification Rationale Class II (performance standards). ## Recent Cleared Devices (18 of 18) | Record | Device Name | Applicant | Decision Date | Decision | | --- | --- | --- | --- | --- | | [K924882](https://fda.innolitics.com/submissions/MI/subpart-d%E2%80%94serological-reagents/GLZ/K924882.md) | TOXOPLASMA IGM IFA TEST SYSTEM | Zeus Scientific, Inc. | Mar 23, 1993 | SESE | | [K880007](https://fda.innolitics.com/submissions/MI/subpart-d%E2%80%94serological-reagents/GLZ/K880007.md) | TOXO IGM TEST | Gull Laboratories, Inc. | Mar 17, 1988 | SESE | | [K850591](https://fda.innolitics.com/submissions/MI/subpart-d%E2%80%94serological-reagents/GLZ/K850591.md) | FIAX TOXO-M ANTIBODIES TEST KIT | Intl.
