ColorSeed™ is a revolutionary internal certified standard for Cryptosporidium and Giardia testing.

Each ColorSeed™ tube has a mean between 98 and 102 of inactivated Cryptosporidium oocysts and between mean 98 and 102 inactivated Giardia cysts (with a standard deviation of 2.5 or less) in 1ml of saline solution. All oocyst and cysts are permanently labelled with a red florescent dye.

ColorSeed™ takes quality control of testing Cryptosporidium and Giardia to a revolutionary level by including a control sample in every sample being tested. When added to the test sample, it provides the analyst with an internal quality control parameter against which the performance of every test can be measured.
