Parasite Examination Flashcards
Physical examination; based on signs
and symptoms of the patient/s exhibited.
Clinical Diagnosis
Based significantly on laboratory reports
or test results
Laboratory Diagnosis
- Important procedure in evaluating a
disease by providing evidence of a new or
unsuspected etiologic agent - Able to confirm a clinical impression that
the condition has a parasitic nature
-Aids the physician with the appropriate
medication and helps in monitoring the
effect of a treatment regimen.
Laboratory Diagnosis
Successful laboratory identification of
parasites requires the knowledge and
practice of laboratory testing in the
pre-analytic, analytic, and post-analytic
steps.
What happens in Pre-analytic testing
- Specimen Collection
-Transport - Labeling
What happens in Analytic testing
Specimen Processing
Post-analytic
- Interpretation
- Reporting of results
the two methods for identifying parasite infections
➢ Serologic test
➢ Microscopic
the most common procedure performed in
the area of parasitology
