Is it true the most accurate test for h pylori is having a stool sample and not blood test?

Testing for H.pylori: H.Pylori status is checked with the intention of treating the infection to eradication, when found. If persistent or recurrent, please ask your doctor to prescribe a drug combination different than your initial regimen--your h.Pylori may be resistant to the first antibiotics used. Serology alerts us to past infection; stool testing, breath testing, stomach biopsy identify active bacteria.
