“…Red blood cells (RBC), or erythrocytes, representing discoid cells with thick rim and thin sunken center, are the most abundant among blood cells. Different blood abnormalities at different stages alter the original biconcave shape of erythrocytes into different morphologies (Ahmadzadeh, Jaferzadeh, Lee, & Moon, 2017; Jaferzadeh & Moon, 2016; Moon et al, 2013; Singh, Srivastava, & Mehta, 2020). Apart from studies on clustering irregular shapes of erythrocytes at different duration of storage from the sample collected from healthy person (Ficarra et al, 2013; Piety, Reinhart, Pourreau, Abidi, & Shevkoplyas, 2016; Suwalsky et al, 2004; Suwalsky, Mennickent, Norris, Villena, & Sotomayor, 2006), there are various other articles investigating the erythrocyte morphologies from the sample collected from patients (Buys et al, 2013; Kurantsin‐Mills, Samji, Moscarello, & Boggs, 1982; Oprisan, Stoica, & Avadanei, 2017).…”
