What Is an Albert Stain Test?
The Albert stain test is a microbiological staining technique used to identify Corynebacterium diphtheriae, the bacterium responsible for diphtheria. A swab sample is collected from the throat, nasal passage, or wound, then stained and examined under a microscope. It is also known as the Diphtheria Stain Test. Doctors typically prescribe this test when a patient shows symptoms that suggest a possible diphtheria infection.
What Does an Albert Stain Test Measure?
The test examines a swab sample under high magnification to identify specific features of Corynebacterium diphtheriae. The key elements observed are listed below:
| Component | What It Tells Us |
|---|---|
| Metachromatic granules (volutin granules) | Bluish-black granules found at the poles of the bacteria; their presence is a key marker for C. diphtheriae |
| Bacterial morphology | Green-coloured, rod-shaped bacteria arranged at angles resembling the letters "L", "V", or a Chinese letter pattern |
| Corynebacterium diphtheriae | The bacteria that cause diphtheria, a serious infection of the nose and throat |
Why Is an Albert Stain Test Done?
This test is ordered when a doctor suspects diphtheria based on a patient's symptoms or exposure history.
Common Symptoms That May Require This Test
The following symptoms are among the most common reasons a doctor may request the Albert stain test:
- Sore throat and fever
- A thick, grey coating (called a pseudomembrane) in the nose or throat that makes breathing and swallowing difficult
- Difficulty swallowing (dysphagia)
- Swollen glands (enlarged lymph nodes) in the neck
- Headache
- Difficulty breathing
Conditions This Test Can Help Detect
The test can assist in identifying the following conditions:
- Respiratory diphtheria, a serious bacterial infection of the nose and throat that can lead to complications such as heart muscle inflammation (myocarditis) and nerve damage (neuropathy).
- Cutaneous diphtheria, a milder form of the infection that causes skin sores or shallow ulcers.
- Airway obstruction caused by the growth of a diphtheria pseudomembrane.
How to Prepare and What to Expect
The Albert stain test procedure is relatively simple and straightforward. The points below cover everything you need to know before your appointment.
Do You Need to Fast?
No fasting is required before this test. However, you should avoid eating, drinking, or using antiseptic mouthwash for at least one hour before the swab is taken, as these can interfere with the sample quality.
Practical Tips Before Your Test
Keep the following points in mind before your appointment:
- Avoid antiseptic mouthwash or oral rinses for at least one hour before collection.
- Tell your doctor if you are currently taking any antibiotics, as this may affect the result.
- Avoid eating or drinking for at least 1 hour before the swab test.
- Be aware that diphtheria spreads through coughing, sneezing, and close contact, so inform those around you if infection is suspected.
Step-by-Step Procedure
The sample collection process for the Albert stain test is simple and takes only a few minutes. Here is what happens at each stage.
- A trained healthcare professional will ask you to tilt your head back and open your mouth wide.
- A sterile cotton swab is gently rubbed across your throat, tonsils, or the affected area to collect the sample.
- The swab material is spread onto a glass slide in the laboratory.
- The slide is treated with Albert's staining solution and left for 5 to 7 minutes, then washed with a second solution for 1 to 2 minutes.
- The slide is dried, and a drop of immersion oil is applied before examination under a high-powered microscope.
- A trained laboratory professional examines the slide and documents the findings for your report.
Factors That Can Affect Accuracy
Certain factors may reduce the reliability of the Albert stain test result. These include the following.
- Using antiseptic mouthwash before the swab is taken.
- Recent or ongoing antibiotic use.
- Poor swab technique during sample collection.
- Microbial contamination of the sample.
- Slides interpreted by personnel without adequate training in staining techniques.
Understanding Your Albert Stain Test Results
Your results should always be discussed with your doctor, who will consider them alongside your symptoms and medical history. The table below outlines how results are generally interpreted.
| Parameter | Result | Interpretation |
|---|---|---|
| Corynebacterium diphtheriae | Not detected (Negative) | Normal; no diphtheria-causing bacteria found in the sample |
| Corynebacterium diphtheriae | Detected (Positive) | Abnormal; bacteria resembling C. diphtheriae are present; further testing may be needed |
These ranges are general guidelines. Your doctor will interpret your results based on your age, health history, and other factors. Always consult a qualified healthcare professional for personalised medical advice.
How to Maintain Healthy Levels
The following general wellness steps can help reduce your risk of diphtheria:
- Ensure your vaccinations are up to date. The diphtheria toxoid vaccine, usually given alongside tetanus and pertussis vaccines, is part of India's routine childhood immunisation schedule.
- Practise good hand hygiene and avoid close contact with anyone showing symptoms of a respiratory infection.
- If you are travelling to areas where diphtheria is more common, check your immunisation status in advance.

Frequently Asked Questions
The Albert stain test is a laboratory diagnostic technique used to detect Corynebacterium diphtheriae, the bacterium responsible for diphtheria. It works by staining the organism’s characteristic intracellular granules, making them clearly visible under a microscope. Doctors usually recommend this test when patients present with symptoms such as a sore throat, fever, difficulty swallowing, and enlarged lymph nodes in the neck.
During the test procedure, a trained healthcare professional uses a sterile cotton swab to collect a sample from your throat, tonsils, or any visibly affected area. The entire process is very quick, usually lasting only a few seconds. It is generally well tolerated by most individuals, though a small number of people may briefly experience a mild gag reflex or slight discomfort. This sensation is temporary and typically subsides almost immediately once the swab is removed.
Fasting is not required prior to sample collection. However, it is important to take certain precautions to ensure the accuracy of the test results. Specifically, you should refrain from eating any food, drinking beverages, or using antiseptic mouthwash for at least one hour before the sample is collected. Avoiding these activities helps prevent potential interference or contamination that could affect the sample's quality.
The Albert stain test result is typically available on the same day as sample collection. The exact turnaround time may vary slightly depending on the collection location, timings and laboratory.
A positive result means that bacteria resembling Corynebacterium diphtheriae were found in your sample, which suggests a possible diphtheria infection. Your doctor will advise on the next steps, which may include further confirmatory tests. Anyone who has been in close contact with you may also need to be assessed.
The Albert stain is a presumptive test, meaning it provides an early indication rather than a definitive diagnosis. A bacterial culture and a toxigenicity test (Elek test) are usually done alongside it to confirm the infection and assess whether the bacterial strain produces the diphtheria toxin.
This test is recommended for anyone showing signs of possible diphtheria, such as sore throat, fever, enlarged lymph nodes, or a grey coating in the throat. Such individuals should speak to a doctor about their symptoms. It is particularly relevant for unvaccinated individuals and those who have had close contact with a confirmed or suspected diphtheria case.
