Vaginal self-test: how do you know if you have a vaginal infection?

An intimate change can quickly become stressful. An unusual vaginal odour, different vaginal discharge, itching or simply a feeling of discomfort... and often, you do not really know how to read these signs.

The vaginal self-test is there to help you see more clearly.

By measuring vaginal pH and taking other indicators into account, such as biomarkers, it helps you place your intimate balance more accurately.

This can guide you in understanding your symptoms and help you decide whether it is better to see a health professional.

Why vaginal symptoms are hard to make sense of

Understanding your vaginal symptoms is not always straightforward, in particular because several imbalances can cause very similar signs.

What can the different vaginal symptoms correspond to?

In practice, many women describe the same signs:

• Itching: often associated with a vaginal yeast infection, especially when it is pronounced and persistent

• Thick, whitish discharge: generally linked to a yeast infection, most often without a strong odour

• An unusual odour: frequently seen with bacterial vaginosis

• Thinner or greyish discharge: often characteristic of vaginosis

• Mild discomfort or diffuse irritation: can correspond to a microbiome imbalance, with no identified infection

The important point is that these symptoms do not all correspond to the same situation.

In practical terms, a yeast infection mainly causes itching, whereas vaginosis is often linked to a more pronounced odour and a higher pH.

In this context, it becomes hard to know precisely what you have without an objective indicator, especially since vaginal discharge changes naturally across the cycle.

Vaginal self-test: how does it work?

A vaginal self-test rests on a simple principle: analysing certain indicators present in the vaginal environment to better understand what is going on.

The vaginal pH test

The vaginal pH test is the analysis most commonly used in self-tests. It quickly assesses whether the vaginal environment is broadly balanced or disturbed.

It is simple to use:

1. Take a vaginal sample

2. Apply it to the strip

3. Observe the colour

4. Compare it with the scale

Vaginal pH is a useful indicator, because a healthy vagina is naturally acidic. A rise in pH can therefore point to an imbalance, particularly a bacterial one.

General interpretation:

• Acidic pH: vaginal environment generally balanced

• Higher pH: possible microbiome imbalance

However, this indicator alone does not allow a complete interpretation.

For example:

• A vaginal yeast infection can appear with a still-normal pH

• A high pH does not always indicate a specific infection

and some imbalances can exist without a clear change in pH.

In other words, pH gives you a first piece of information, but it does not let you pinpoint where the symptoms come from.

The other indicators analysed (biomarkers)

To go further, some self-tests also analyse other biological indicators, called biomarkers.

A biomarker is simply a measurable signal that helps identify an imbalance, unusual bacterial activity or a reaction from the body.

They make it possible to assess:

• The balance of the vaginal microbiome, indicating whether the flora is preserved or disturbed

• The activity of certain bacteria, which can point to a bacterial imbalance

• The body's response, particularly in cases of inflammation or infection

Today, some self-tests combine several of these indicators to offer a fuller reading, as is the case with certain solutions available in pharmacies or online, which integrate several biomarkers to refine the analysis.

What can a vaginal self-test reveal?

Faced with intimate symptoms, one question comes up often: is this a simple imbalance or something that needs particular attention?

A vaginal self-test does not make a diagnosis, but it provides objective elements for better understanding what is going on.

In concrete terms, a self-test can indicate:

• Whether the vaginal environment appears balanced or disturbed

• Whether certain signs point to a bacterial imbalance

• Whether the body is showing signs of a reaction, such as inflammation

• Whether the results are consistent with the symptoms you feel

This information does not give a diagnosis, but it helps you read your symptoms better and avoid some common confusions.

For example, itching does not always correspond to a yeast infection, and an unusual odour is not systematically linked to a severe infection. The self-test is precisely there to add nuance to these interpretations.

It therefore sits as an intermediate tool: between how you feel and a consultation, to better understand what is going on before acting.

With fuller vaginal self-tests, such as those offered by Santelle, several biomarkers can be analysed in parallel.

In particular this provides indications about:

• The overall balance of the vaginal microbiome

• Whether or not there is unusual bacterial activity

• Signs of a reaction from the body, such as inflammation

• Whether the natural protective mechanisms are holding up

How do you use a vaginal self-test?

It is generally simple and quick to use.

1. take a vaginal sample using the swab provided

2. apply the sample to the test area (strip or cassette)

3. wait a few seconds for the reaction to take place

4. compare the result with the scale or the reference points shown

Depending on the test, several indicators can be analysed at once, which gives a fuller reading.

Interpretation should always take your symptoms into account.

If in doubt, if discomfort persists or if symptoms are unusual, it is still better to see a health professional.

What should you do after a vaginal self-test?

After a self-test, the main thing is to interpret the results carefully and place them in context.

A few useful reference points:

• Watch how the symptoms develop over the following days

• Avoid drawing conclusions too quickly from a single result

• Cross-check the results against the signs you feel (discomfort, odour, discharge...)

If in doubt, the advice of a health professional remains the reference.

Today, some devices also offer follow-up through an app.

This lets you keep your results, watch how they change over time and better understand the variations linked to your cycle or to everyday factors.

Conclusion: understanding your vaginal balance with a vaginal self-test

Faced with intimate changes, it is normal to have questions. Symptoms are not always easy to interpret, and it can be hard to know how to react.

The vaginal self-test provides a first level of understanding. It does not replace medical advice, but it helps you place what is happening, with concrete reference points.

In practice, it can help you:

• Better understand certain symptoms

• Avoid hasty interpretations

• Decide on the next steps more calmly

Above all it is a tool for regaining confidence in situations that so often cause doubt.

If symptoms persist, are unusual or are troublesome, it remains essential to see a health professional.

But in many situations, better understanding your vaginal balance is already an important first step.
