Perinatal diseases which can be passed from a mother to child are known to cause complications during pregnancy and congenital symptoms at birth. Therefore, a ToRCH screen is often carried out in the first few months of pregnancy, testing for Toxoplasmosis, Rubella, Cytomegalovirus and Herpes Simplex Virus. Traditionally, control solutions are created from the serum of someone suffering with a disease, in this case, someone with Rubella. However, since most people are vaccinated for Rubella at a young age it is often difficult to source a native material. This great alternative to native disease state plasma boasts proven performance, high reproducibility and secure, long term supply.
