If low-tech home pregnancy test stick isn’t enough, ThinkGeek now resells a USB version of the kit, dubbed PTeq, for just $17.99. You basically follow the same procedures as you would with a standard kit except the stick goes into a USB port after it becomes contact with your urine.
The USB connection starts the electrospray ionization process on the device, creating a spectrograph of your urine. The mass spectrometry software then will give you an analysis of your hormone levels so you can clear your calendar in advance after reviewing the data. There’s a 99% accuracy in detecting hCG, hCG-H and LH, but these hormones don’t necessarily indicate pregnancy or ovulation. FYI, the PTeq is Leopard friendly also.
Help spread the word. You're awesome for doing it!
