When your child develops a rash, it can be worrying—but most of the time, it’s nothing serious. Viral rashes, heat rash, or allergic reactions are common in babies and young children. However, some rashes can be a warning sign of something much more dangerous: meningococcal septicaemia, a life-threatening form of meningitis. That’s where the meningitis glass test comes in.

At Luxtons Pharmacy, we believe parents should feel confident knowing what to look out for and when to act. This guide will help you understand the difference between everyday rashes and the warning signs of meningitis, and how to perform the glass test correctly.

What Is the Meningitis Glass Test?

The meningitis glass test is a simple at-home check used to help identify one of the symptoms of meningococcal septicaemia: a non-blanching rash. This rash is caused by bleeding under the skin and does not fade when pressure is applied.

To do the test:

1. Take a clear glass or tumbler.

2. Press the side of the glass firmly against the rash.

3. Look through the glass—if the rash does not fade, it could be a sign of meningitis or septicaemia.

4. If the rash is still visible under pressure, seek immediate medical attention by calling 999 or going to A&E.

The glass test can be done on any part of the body where the rash appears, including the limbs and trunk.

What Does a Meningitis Rash Look Like?

A meningitis rash typically appears as small red or purple pinpricks that can quickly spread and turn into blotches. It often starts on the torso, arms, or legs, but it can occur anywhere. Unlike a normal rash, it does not disappear when pressed with a glass—hence the importance of the glass test.

However, it’s crucial to remember: not all cases of meningitis present with a rash, especially in the early stages. That’s why it’s important to consider other symptoms too.

Symptoms of Meningitis and Septicaemia

The signs of meningitis can be different depending on age, but here’s a checklist to help you recognise when something may be wrong:

In babies and young children:

• –> Fever with cold hands and feet

• –> Refusing feeds or vomiting

• –> Irritability and high-pitched crying

• –> Floppiness or unresponsiveness

• –> Bulging soft spot (fontanelle) on a baby’s head

• –> Rapid breathing

• –> Pale or mottled skin

• –> Seizures or fits

In older children, teenagers, and adults:

• –> Severe headache

• –> Stiff neck

• –> Sensitivity to light (photophobia)

• –> Confusion or drowsiness

• –> Difficulty concentrating

• –> Muscle or joint pain

• –> Rash that doesn’t fade under pressure

If your child has any of these symptoms—with or without a rash—you should seek urgent medical advice.

Rash or Something Else?

Many childhood rashes look alarming but are caused by mild conditions such as viral infections (e.g., roseola, hand-foot-and-mouth), allergies or eczema, heat rash, or insect bites.

These rashes usually fade under pressure, improve with antihistamines or cooling measures, and are not accompanied by other serious symptoms.

The glass test is one useful tool, but it should not be used in isolation. Trust your instincts—if your child seems very unwell, don’t wait for a rash to appear before getting help.

What Should You Do If You’re Worried?

At Luxtons Pharmacy, we’re here to support parents and carers with advice and reassurance. If you’re unsure whether your child’s rash is a cause for concern, use the meningitis glass test to check whether the rash fades under pressure.

Be sure to monitor for other symptoms—especially fever, lethargy, and breathing changes. Speak to a pharmacist or GP if symptoms are mild but persistent.

Call 999 or visit A&E immediately if your child has a non-blanching rash, is very drowsy, or shows any serious symptoms listed above.

Can Vaccines Prevent Meningitis?

Yes—there are vaccines available that protect against several strains of meningitis, including:

• –> MenB (offered to babies on the NHS)

• –> MenACWY (offered to teenagers and some travellers)

• –> Hib/MenC (included in the childhood vaccine schedule)

If you’re not sure whether your child is up to date, we can help review their records and arrange private vaccines through our travel clinic if needed.
