1. A fluid sample testing apparatus comprising:
a housing with a fluid collector tube;
a sample holding container in fluid communication with the fluid collector tube and removably secured to the fluid collector tube;
a fluid collector, wherein the fluid collector has an elongated stem and is adapted for insertion into the fluid collector tube and upon insertion and penetration into the fluid collector tube pressure is generated to release fluid from the fluid collector into the sample holding container;
a gasket positioned in the fluid collector tube having an upper portion engaging a wall of the fluid collector tube and a lower portion of smaller diameter than the upper portion extending into an opening of the sample holding container, wherein the gasket is positioned at an upper location in the fluid collector tube upon insertion of the fluid collector into the fluid collector tube, wherein the gasket is positioned at a lower location in the fluid collector tube after insertion of the fluid collector into the fluid collector tube and at the lower location a surface of the gasket that is positioned between the upper portion and the lower portion engages a top surface of the sample holding container and forms a seal with the sample holding container, wherein air passes outside of the apparatus from the fluid collector tube around an upper portion of the sample holding container before the gasket is positioned at the lower location.
