Gram stain of tissue biopsy
Normal Values
The presence or type of organisms depends on the particular tissue being biopsied. Some tissues in the body are sterile, such as the brain, whereas other tissues normally contain organisms. Note: Normal value ranges may vary slightly among different laboratories. Talk to your doctor about the meaning of your specific test results.
What do Abnormal Results Mean?
Abnormal results usually indicate an infection in the tissue site. Further tests, such as culturing the biopsied material, are frequently needed to identify the specific type of organism involved.
