Which of the following statements regarding diagnosis of Malaria are true?

- Option - 1 - False - Thin film is used to detect species of plasmodium causing infection As thin film is air dried in 10 mins & fixed with methanol, morphology of parasite is not destroyed, hence species can be identified - Option - 2 - False - Thick film is used to detect malarial infection & its concentration in blood. As thick film is dried slowly by taking 30 mins, hemolysis can occur resulting in destroying the morphology of parasite. Hence, species cant be determined. - Option - 3 - True - Jaswant Singh Bhattacharya (JSB) Stain is used in both blood films - Option- 4 - False - As the sensitivity of microscopy is high, It is possible to detect malarial parasite at low densities.
