Tests and diagnosisBy Mayo Clinic staff
Evaluating a bedsore
To evaluate your bedsore, your doctor will:
- Determine the size and depth of the ulcer
- Check for bleeding, fluids or debris in the wound that can indicate severe infection
- Determine if there are odors that indicate an infection or dead tissue
- Assess the area around the wound for signs of spreading tissue damage or infection
- Check for other pressure sores on the body
Questions from the doctor
Your doctor may ask you or your caregiver questions such as:
- When did the pressure sore first appear?
- What is the degree of pain?
- Have you had pressure sores in the past?
- How were they managed, and what was the outcome of treatment?
- What kind of care assistance is available?
- What is your routine for changing positions?
- What medical conditions have been diagnosed, and what is the current treatment?
- What is your normal daily diet?
- How much water and other fluids do you drink each day?
Your doctor may order the following tests:
- Blood tests to assess your nutritional status and overall health
- Tissue cultures to diagnose a bacterial or fungal infection in a wound that doesn't heal with treatment or is already a stage IV wound
- Tissue cultures to check for cancerous tissue if it's a chronic, nonhealing wound
