COVID-19 Rapid Antibody Test

TEST_1
Thanks to the healthcare professionals at Semesur Assistance and our rapid diagnostic testing, you can find out whether you currently have—or have previously had—COVID-19.

Are you experiencing symptoms and want to know quickly whether you have COVID-19? Has your business resumed operations and you want to do so with the highest level of health protection? Are you concerned that you may have been exposed to the virus and would like to know whether you have developed COVID-19 antibodies?

In response to the COVID-19 public health emergency, Semesur Assistance joined the efforts of healthcare providers supporting the fight against the pandemic. Through our diagnostic testing service, we offered a fast and efficient way to help answer these important questions.

Our healthcare professionals perform rapid COVID-19 antibody tests (IgG/IgM), designed to determine whether a person has developed antibodies following a recent or previous SARS-CoV-2 infection.

Testing is carried out at our Jerez de la Frontera clinic by appointment. For added convenience and safety, samples are collected without patients having to leave their vehicle, requiring only a simple finger-prick blood sample.

For companies wishing to screen a larger workforce, our medical team can also provide on-site testing, making the process faster and more convenient for employees while minimising disruption to business operations.

These tests are manufactured by a Swiss laboratory and are designed to measure the body's immune response to COVID-19. Following a medical assessment by our healthcare professionals, the serological test determines whether antibodies against SARS-CoV-2 have been produced.

According to the manufacturer's validation studies, the reported performance of the test is:

  • IgM antibody sensitivity: 91.8%

  • IgG antibody sensitivity: 100%

During sample collection, our healthcare professionals follow strict infection prevention procedures to ensure maximum safety for both patients and staff. All personal information is handled in accordance with applicable data protection regulations.

Test results are available within 24 hours and are communicated directly to the patient via email or WhatsApp.

It is important to remember that antibody testing represents only one part of the diagnostic process and should always be interpreted by a qualified healthcare professional.

If a patient's result suggests a recent or previous COVID-19 infection, they should contact their primary care physician or relevant healthcare provider to ensure appropriate clinical assessment and follow any public health guidance in place at the time.
