A review on point of care tests in parasitology

Infectious diseases can be of serious public concerns because of its transmissibility. The parasitic infectious diseases in particular are often seen as neglected diseases of poverty. The diagnostic tests for parasitic diseases barring malaria are not easily available specially in low resources settings where they are needed most. The conventional mode of diagnosis based on centralized laboratory is time consuming and resource intensive. The modern-day medicine has shifted the focus to patient care. The use of point of care tests (POCT) has increased worldwide because they provide rapid diagnosis within the consultation time that too near patient care areas. This is very useful for starting initial treatment. These POCT provide excellent solution for rural and hard to reach areas where parasitic diseases are most prevalent. Despite the high demand, a relatively limited number of validated rapid diagnostics are commercially available for parasitic infections.

This review aims to discuss various POCT available for these neglected parasitic diseases. Accurate detection of parasitic infection underpins a holistic approach to its control and management. The POCT can also be used to screen mass population to detect asymptomatic reservoirs and monitor interventions planned for elimination programs for many parasitic diseases. Recently focus is on integrated platforms and analysis of multiple analytes from single sample. Researchers are striving to produce POCT based on innovative technology such as lab-on-chip that can be made more affordable and suitable for low resource settings.
