- Thick and Thin Blood Smear for Malaria Diagnosis
The thin blood film should always be examined to identify parasite species or mixed infections after examining the thick film Unlike the thick film, the thin film allows visualization of parasite and red cell morphology Perform an examination at the feathery end or edge of the thin film
- MALARIA PARASITE COUNTING - World Health Organization (WHO)
Performing a parasite count on a thick fi lm and calculating parasite density Place the glass slide on the microscope, with the label to the left Determine the presence of malaria parasites and their species and stages, and record (see MM-SOPs 6b and 08)
- Malaria Diagnostic Tests - CDC
Microscopic examination of blood films is the gold standard for laboratory confirmation of malaria parasites A Rapid Diagnostic Test (RDT) is an alternate way of quickly establishing the diagnosis of malaria PCR can help identify the Plasmodium species to ensure proper treatment
- Thick blood film examination for Plasmodium falciparum malaria has . . .
Microscopy of thick blood films is the usual diagnostic test for Plasmodium falciparum malaria Density is usually assessed by thick films, either by counting parasites per microscope field, or by counting parasites per hundred white blood cells [1]
- Thick vs Thin film comparison - MalariaETC
There is no single correct choice of staining, essentially the thin film has many advantages in terms of ease of preparation, staining and identification In contrast the thick malarial film offers a single but significant advantage: that of superior sensitivity for parasite detection
- Thick and Thin Blood Smear for Malaria Diagnosis
Thick and thin blood smears are laboratory techniques used to diagnose various blood-borne infections, including malaria and other parasitic diseases A thick blood smear involves placing a drop of blood on a microscope slide and spreading it in a circular motion to create a thick film
- MICROSCOPY EXAMINATION OF THICK AND THIN BLOOD FILMS FOR IDENTIFICATION . . .
4 2 Determining whether a thick film contains malaria parasites and identifying the species 1 Examine the thick film under the oil immersion objective, field by field, horizontally or vertically 2 Read a minimum of 100 fields before declaring that no malaria parasites were seen 3 If parasites are found, scan additional
- CDC - DPDx - Diagnostic Procedures - Blood Specimens
Determination of “No Parasites Found” (NPF): For malaria diagnosis, WHO recommends that at least 100 fields, each containing approximately 20 WBCs, be screened before calling a thick smear negative
