#  Meningitis Rash & the Glass Test: When to Call 999

Quick answer — What if the rash fades under the glass? 

 
Press a clear glass firmly on the rash — if spots do not fade under pressure, treat it as an emergency and call 999. Do not wait for a rash: fever with stiff neck, dislike of light, unusual drowsiness, cold hands and feet, or a child who is not themselves also needs urgent help. On darker skin check palms, soles and inside the eyelids.

    
Who should skip this

 
Do not use this instead of 999 if you suspect meningitis. Skip it if you wanted a general rash guide.

The glass test is the one first-aid skill every UK parent should be able to do half-asleep. It does not diagnose meningitis on its own — it tells you when to **stop waiting**.

## How do you do the glass test?

* Use a clear glass.
* Press the side firmly against the rash.
* If the spots **still show through the glass** (do not fade), call **999**.

That is a **non-blanching** rash. Meningitis Research Foundation and NHS both treat this as emergency territory when a child is unwell.

## What does a meningitis-type rash look like?

**Pinprick red, purple or brownish spots or bruise-like blotches.** It can appear late. On brown or black skin it is easier to miss — check **palms, soles, eyelids and the roof of the mouth**.

## Should you wait for a rash before calling 999?

**No.** NHS immediate-action fever red flags include stiff neck, dislike of bright light, a first seizure, cold hands/feet, colour change, drowsiness, extreme agitation/confusion, or breathing difficulty — with or without a rash. Pair this page with [when to take a baby with a fever to A&E](/baby/when-to-take-baby-fever-to-ae).

If you are logging temperatures while you wait for advice, use a [digital armpit thermometer](https://www.amazon.co.uk/s?k=digital+baby+thermometer+armpit&tag=clevermum0c-21) — forehead strips alone are not enough.

## What should you do while waiting for help?

* Call 999 and follow dispatcher instructions
* Note the time symptoms started
* Do not give aspirin under 16
* Stay with your child

## What do UK parents actually say about this?

**Parents who have called 999 for a non-blanching scare almost always say the same thing afterwards: they would rather feel foolish in A&E than wait for a “proper” textbook rash.** The glass test ends the debate in the kitchen.

## Who should skip “monitor overnight”?

**Skip overnight watching if the rash does not fade, or if fever comes with neck stiffness, photophobia, seizure, colour change or unresponsiveness.** Those are not next-GP-day problems.

**What we’d change:** viral graphics that show only bright-red spots on pale skin — teach parents to check paler sites on deeper skin tones.

   
## What questions come up most?

    What if the rash fades under the glass?   
 A fading rash is less concerning for meningococcal septicaemia, but an unwell child with fever still needs advice — call 111 or your GP the same day. Re-check the rash; it can change. 

   Can meningitis happen without a rash?   
 Yes. A rash can appear late or not at all. Act on breathing, alertness, neck stiffness, seizures and colour change even if the skin looks clear.
