Dermatologists use the glass test to identify dangerous causes of rashes including meningitis and vasculitis. Press a clear glass against the rash. Most rashes will blanch to be skin color. Many serious rashes including the one associated with menignitis will not blanch. If accompanied by fever or other symptoms, seek medical care right away. #glasstest #meningitis #dermtips #dermatologist #mothers #parents #fyp

Common Fungal Rash #dr explains

If you see a rash on your little one, perform this check 👇 Does the rash blanch? A good way to check for this by using a clear glass and rolling it over the rash. If the rash turns white that means it blanches. A non-blanching rash doesn't turn white when pressed on. If the rash is non-blanching it means there is bleeding beneath the skin and there are tests that should be done to rule out anything serious causing this. We would love to share more examples of non blanching rashes from little on
