Blood pH measures how acidic or alkaline the blood is, and is reported as part of a blood gas panel alongside carbon dioxide and oxygen measurements. The body holds it within a narrow range.

Also known as: ph, blood ph, venous ph, arterial ph, ph venous, ph arterial, blood gas ph, ph (venous blood gas)
Reference range: 0 — 0 pH (Source: ABIM)
Standard unit: pH
High values may indicate

Low values may indicate
A lowered blood pH (acidosis) can accompany breathing that removes too little carbon dioxide, poorly controlled diabetes, kidney conditions, or severe infection.
Frequently asked questions
- What is a normal pH (Blood Gas) level?
- A typical reference range for pH (Blood Gas) is 0 — 0 pH (source: ABIM). Reference ranges vary by laboratory, age, and sex, so always compare against the range on your own lab report.
- What units is pH (Blood Gas) measured in?
- pH (Blood Gas) is most commonly reported in pH. Labs in different countries may use other units — you can convert between them with BloodId's blood test unit converter.
- Where do pH (Blood Gas) reference ranges come from?
- BloodId uses ABIM standard reference ranges and educational information from MedlinePlus (see our methodology). Reference ranges still vary by lab, age, and sex, so always compare against your own report.
- Can I track pH (Blood Gas) over time?
- Yes. Upload results from any lab and BloodId charts your pH (Blood Gas) over time against its reference range, so you can see whether the trend is rising, falling, or stable.
