The air sample capture assembly including a test tube containing a vacuum and having a rubber stopper that separates the vacuum contained within the test tube from the needle assembly connected to the blow tube. The rubber stopper is capable of being pierced by a needle of the needle assembly at a predetermined time. Additionally, the invention includes a method of using the air sampling device for obtaining a sample of air from a person's lungs. The method comprising: a first step in which the person blows a predetermined volume into the blow tube and a second step in which the rubber stopper separating the needle assembly from the inside of the test tube containing the vacuum is pierced after the predetermined volume is expelled by the person into the blow tube and a portion of the air blown by the person is captured in the test tube and the needle is subsequently withdrawn and the rubber stopper reseals itself or is sealed.
