Express tests: how the habit of checking your health has changed

Not so long ago, diagnostics were associated with sterile offices, queues and long waits for results. Today, more and more often, the examination begins with a rapid test - in a pharmacy, in a private laboratory or even at home. Rapid tests have become part of everyday medicine, and this transformation is changing the rules of the game for doctors, patients and laboratories themselves.

What has changed?

A few years ago, rapid tests were associated mainly with pregnancy tests or glucometers for diabetics. Now the list has expanded several times. They are used in cases of suspected viral infections, heart disease, and even in assessing liver or kidney function. The reason is not only convenience, but also a strategic need: to quickly determine whether hospitalization is required or outpatient observation is sufficient.

Who uses rapid tests?

• Patients — for preliminary self-diagnosis at home

• Family doctors — as a tool for rapid assessment of the patient's condition

• Ambulance — for urgent screening in the field

• Clinics — to save time before vaccination, minimally invasive procedures

• Companies — during medical examinations of employees

Types of rapid tests that really change the approach

New generation blood glucose meter

Glucose level — without a finger prick, via a sensor that works in real time. Data is automatically saved in the mobile application.

Rapid troponin test

Helps quickly rule out or confirm myocardial infarction in patients with chest pain — in 10 minutes.

Rapid infection diagnostic panel

Combination of markers: hepatitis, HIV, syphilis — one blood sample, one cassette test, one result.

Visual sensor test for liver enzymes

It is being developed as a technology of the future: changing the color of the reagent directly on the test chip.

What is important to know about quality

Not all rapid tests are equally accurate. Some are certified and undergo rigorous validation, while others are only indicative. The quality depends on:

• method (immunochromatography, electrochemistry, photometry)

• manufacturer (there is a big difference between CE marking and internal self-test)

• correctness of execution (time, temperature, sample, storage)

An area where rapid tests have already become the standard

• Pediatrics: rapid tests for rotavirus, streptococcus, adenovirus

• Cardiology: troponins, BNP

• Reproductive medicine: ovulation test, hCG

• Infectious diagnostics: Covid-19, flu, hepatitis

• Emergency medicine: determination of electrolytes, creatinine, pH

What will happen next?

The trend is clear: the rapid test is no longer just a convenient tool and is becoming part of the medical journey. In the future, most of these tests will be integrated into mobile platforms, automatically transmitting data to the doctor and allowing patients to monitor their progress without leaving home.

Express analyses are not a compromise between accuracy and speed. They are a technology that provides a timely reference point. And the right decision for a doctor, as always, begins with correctly collected facts.
