The results of the carbon 13 breath test to check for H. pylori are categorized into four grades, denoted as grades 0 to 3.
The carbon 13 breath test is divided into four main grades, a result of less than 4 dpm/mmolCO₂ is known as grade 0, a result value of 4 to 20 dpm/mmolCO₂, grade 1, a result value of 20 to 40 dpm/mmolCO₂, grade 2, and a result value of 40 dpm/mmolCO₂ or more, also known as a strong positive, and is indicated by three plus signs, grade 3.
