Elevated Carbon Monoxitde in blood related to HP?

Breath tests are the most accurate way of detecting H.pylori without actually having an endoscopy (stomach examination). Breath tests are especially useful after treatment to make sure H.pylori is cured. Urea breath tests are known to be completely harmless. Either C14-urea or C13-urea tests are used. Read about them at the diagnosis section at http://www.helico.com/diag_breath.html where a diagram can be found. C14-urea breath tests use a radioactive tracer but such a tiny amount that it can be used safely at any age. It is a 15 minute test, convenient and inexpensive. The C13-urea test uses a stable isotope of carbon which is also harmless but requires two breath samples and takes about 30 minutes. Both tests have accuracy greater than 90%.

Elevated Carbon Monoxitde in blood related to HP?

Post by Siff »

I had several blood tests while diagnosed with HP and my Carboxyhemoglobin levels have constantly been elevated between 3-5% and I am a non smoker. Can this be related to HP overgrowth? I have carried the CO detector everywhere with me for weeks and it never went off.

I also read that HP breath test is based on CO levels produced by HP in stomach, is that true? What if my HP test is false positive and I am actually suffering from CO exposure and not HP?

H. pylori breaks down Urea to give CO2 and NH3.

However, there is no way you can differentiate the amount of CO2 generated by the organism or by yourself.

in breath test, we give patients to swallow a special Urea bill labelled with very small quantity of radioactive material. So when that urea is broken down by H. pylori, the CO2 is radioactive labelled. So when you breath that out, We'll be able to quantify the amount of CO2 created by H. pylori.

I dont think H. pylori correlates to your body CO2 level.

3 weeks after finishing treatment, h.pylori not detected....Carbon Monoxide at 2%....went down slightly but most likely unrelated

Congratulation! free of H. pylori now. Hopefully you can still hop in from time to time to share you after treatment experience with everyone else. Your success is another encouragement for all members here.
