The video shows a close-up of a person's hand wearing a blue glove, holding four test tubes with colored caps. The test tubes are labeled with different colors and text indicating the type of test. The first tube has a yellow cap and is labeled "Negative," the second tube has a purple cap and is labeled "2019-nCoV," the third tube has a blue cap and is labeled "Covid-19," and the fourth tube has a red cap and is labeled "Covid-19 Positive." The background is blurred, but a sign that reads "NO ENTRY" is visible.
