Bangalore Aesthetic Portfolio Template, bally sports detroit announcers; advantages and disadvantages of slide method blood grouping In addition, since thick blood smears are not fixed, they enable parasite views outside the host cells and thus concentrated to increase chances of As ukasz Frckowski explains, the thick smear is used to make the diagnosis of malaria as it is a concentration technique. In 1940 Landsteiner and Weiner injected Blood from the monkey Maccacus rhesus into rabbits and guinea pigs, which resulted in the antibodies production. Later, it was found that an individual who does not have either A or B or both antigens possesses antibodies against these missing antigens and is called blood group O.
