Correct answer is A. Rouleaux formation is characterized by an increase in ESR.
What is Rouleaux formation in ESR?
- Since rouleaux formation is primarily determined by elevated levels of plasma fibrinogen and globulin.
- ESR primarily reflects changes in plasma proteins associated with acute and chronic infections, some tumors, and degenerative diseases.
- Under such circumstances, the ESR value is much higher than 20 mm/h.
- In inflammatory conditions, fibrinogen, other coagulation proteins, and alpha globulin become positively charged, increasing ESR.
