She is using a red marker to label the test tubes. She has a green lanyard around her neck with a logo. She is wearing wireless earbuds. The lab has white walls, white cabinets, and a fluorescent light fixture. The door on the left side has a green sign next to it and the door on the right has the number 312 on it.
