One day, Elizabeth asked Alan Beam and the other employers to join her for a test with the device. Everyone was curious to see what the results were but the Edison test failed. That was the moment when Alan realized that this device was far from hitting the market. Meanwhile, Elizabeth had a deal with Walgreens to release the device for testing but this was delayed several times. In order to avoid losing their partnership, she eventually accepted the proposal which rose more suspicions for the Theranos employers because they saw that nothing was working. In order to try to manage the situation, they decided to cheat. They opened the ADVIA machine used for blood tests and tried to copy the process in miniature. They even thought of asking for a patent for this even though it was ADVIA's property. After that incident, many people left the company including Anjalia Laghari who was the head of the immunoassay group. She knew that things will turn very bad so she decided to hide on her way out her email to Elizabeth and Sunny in which she stated that she doesn't agree with their work since it has high error rates and it would be illegal to release it at this time.
