Covid-19 IgG

Covid-19 IgG

A Covid-19 IgG test detects IgG antibodies against SARS-CoV-2, the virus that causes Covid-19. A positive result may indicate a past infection or an immune response following vaccination, suggesting that your immune system has developed antibodies against the virus.

Doctor's Assessment Included

Covid-19 IgG: what this test measures

This test detects the presence of IgG antibodies directed against SARS-CoV-2 in your blood. IgG antibodies typically develop one to three weeks after infection or vaccination and may persist for an extended period. The test provides a qualitative result indicating whether these antibodies are present.

Covid-19 IgG: why this value matters

Understanding your Covid-19 IgG status can help assess whether you have developed an immune response to SARS-CoV-2 through natural infection or vaccination. However, the presence of antibodies does not guarantee complete protection against future infection. Results should be interpreted by a healthcare professional.

Covid-19 IgG: how the blood test works

Referral: No GP referral needed. After the order we arrange the referral through ZorgDomein, within one business day; orders after 17:00 or at the weekend start on the next business day. ZorgDomein emails a barcode, and that barcode is what the draw site needs.
The draw: A blood draw from a vein in the arm, at a partner laboratory's draw site. No home kit, no finger prick.
Which test: on its own €61,-
Where: 650+ draw sites run by independent laboratories across the Netherlands. Draw sites

Covid-19 IgG: when is testing worthwhile?

Testing may be relevant if you want to know whether you have developed antibodies after a past Covid-19 infection or vaccination. This test is not intended to diagnose an active infection. Consult a healthcare professional for guidance on interpretation.

Covid-19 IgG: lifestyle and this value

Follow current public health guidelines regarding Covid-19 vaccination and boosters. Maintain good hand hygiene and respiratory etiquette. Support your immune system through a balanced diet, regular physical activity, adequate sleep, and stress management. Stay informed about current recommendations from health authorities.

Covid-19 IgG: frequently asked questions

Does a positive Covid-19 IgG result mean I am immune?

A positive result indicates that your immune system has produced antibodies against SARS-CoV-2. However, this does not guarantee complete protection against future infection, as immunity can vary between individuals and may change over time. Consult a healthcare professional for personalised guidance.

Can this test tell whether my antibodies are from infection or vaccination?

Depending on the specific test used, it may or may not distinguish between antibodies from natural infection and those from vaccination. Some tests target the spike protein (produced by both infection and vaccination), while others target the nucleocapsid protein (typically from natural infection only). Your healthcare professional can clarify what your specific result indicates.
