Abrin has a high molecular weight approximately 65 kDa and it is not therefore easily cleared by CRRT. While these tests are sensitive and can provide quantitative results, they require large sample volume, overnight incubation in the case of radioimmunoassay testand more invasive procedures to obtain patient samples [ 211 ].

It is a stable substance and can withstand extreme environmental conditions. A previously healthy month-old, It can also be injected in small pellets and absorbed through contact with the eyes.
