Educational category
Example shown — not medical advice or a diagnosis. Seek urgent care for severe readings or symptoms.
How it works
- Enter the systolic and diastolic numbers from a recent reading.
- The checker compares either value with common adult category thresholds.
- Use the result as an educational prompt, not a replacement for medical care.
The method
The higher-risk applicable range determines the result. For example, a diastolic value of 90 places a reading in the stage 2 category even if its systolic value is lower.
FAQ
Is this a diagnosis?
No. It is an educational categorization of a single reading. Diagnosis requires proper measurement and clinical assessment.
What do the two numbers mean?
Systolic is pressure as the heart contracts; diastolic is pressure while the heart relaxes between beats.
When should I seek urgent care?
Seek urgent advice for very high readings, especially 180/120 or above, or if you have chest pain, trouble breathing, severe headache, weakness, or vision changes.
