Web5 Aug 2024 · Thin and thick blood films have distinct uses. Thick films are typically used for diagnosis and for quantitation of low-parasitemia infections, because the larger blood volume gives a lower limit of detection (LoD) and more stable parasite counts. Thin film are used for species ID, and for quantitation of high-parasitemia infections . WebSo today, we will discuss five reasons why coverslips, and utilizing the right ones, will improve your imaging…. 1. Objectives expect there to be a coverslip in the light path. Objectives are designed to compensate for a coverslip in the light path, and specifically for a 0.17mm thick glass to be in the light path.
