Each kit contains a urine testing kit sample, a 50-ml plastic medical vial, an air-activated heater lasting six hours, a temperature strip, and an instruction sheet with helpful hints and tips. Please note that water is not included. The test sample is supplied in a 50-ml plastic vial with an air-activated heater. The heater takes approximately 15 minutes to heat the water in the vial to a temperature between 90 and 99 degrees Fahrenheit. The temperature strip is highly accurate and reusable, reading between 90 and 100 degrees. Instructions Pour the sample in the small vial into the larger tube. Slowly fill the tube with water to the very top of the tube, screw the blue cap on tightly, and shake until it is completely dissolved. Open the heater package, remove the paper backing from it, and affix it to the back of the tube, directly opposite the temperature strip. Take the sample into the bathroom, check the temperature, and submit it to the facility instead of your own.
