Hey all TB fighters has been pressuring Danaher(a publicly traded company) to lower the prices on its various tests for diseases. These tests make it possible to screen for diseases such as TB, HIV, Ebola, and many more. Unfortunately, they are extremely overpriced, which makes them very hard to access in lower income countries. A few months ago, TB fighters(and John Green) led an online campaign that successfully lowered the price of its MDR-TB test, but now they're pushing for the same thing on all of its tests. If you want to help, you can sign the petition below(also linked a video explaining why it'll work).
