- INTENDED USE
BacterTest™ LABONE HP TEST is used in medical testing to detect and screen for H. pylori in the stomach based on the ability of this bacteria to produce the enzyme urease and hydrolyze urea.
- PRINCIPLES
BacterTest™ LABONE HP TEST is based on the change in pH of the culture medium when bacteria. H.pylori have the ability to produce urease enzyme which quickly decomposes urea into ammonium hydroxide and alkalizes the medium and is identified by pH indicator.
- Before using, the LABONE HP TEST tubes should be removed from the refrigerator and allowed to stabilize at room temperature for 7-10 minutes.
+ Step 01: Use a pen to write the sample name on the tube, then open the BacterTest™ LABONE HP TEST tube cap
+ Step 02: Use forceps to pick up the sample and put it into the tube
+ Step 03: Tighten the cap to keep the tube at room temperature.
+ Step 04: Read the results within 30 minutes by observing the color change of the tube
RESULTS
- Observe the color change of the environment:
+ Pink = Positive (bacteria capable of producing urease)
+ No change color = Negative (bacteria that are unable to produce urease).
BacterLab ensures the quality of each product batch by checking the positive time with urease solution according to concentration:
