Final answer:
A positive test for Loa loa antibodies indicates past exposure to the parasite and does not conclusively show current infection without further follow-up testing.
Step-by-step explanation:
The presence of Loa loa antibodies in a patient's blood test indicates that the individual was exposed to Loa loa at some point, which may suggest past exposure or, less definitively, a current infection. However, since antibodies can persist for months or even a lifetime after an infection has been resolved, the test result does not conclusively indicate that the infection is active without further testing. To ascertain if the infection is current, it's recommended to perform a second test after two weeks; a significant increase in neutralizing titer points towards a new infection. Differentiating between past and current infections is crucial, as it affects the treatment and management of the patient.
