Information:
The quantitative post-exposure serology test for SARS-CoV-2 virus (COVID-19) is based on the detection of specific antibodies in those persons who have overcome infection (symptomatic or asymptomatic) with the virus or are certain or suspected to have been exposed to the virus. In general, antibodies are detected 12-15 days after infection, although it has been shown that antibodies are not generated in a low percentage of the population after exposure.
The sample is taken by conventional blood collection and it is not necessary to come fasting.
The result will be available within 24-48 hours.
Regardless of the result, take hygiene and infection prevention measures (permanent mask and hand hygiene). If you would like your case to be monitored at a Humanline Group centre, please call 956 785 333 to request an urgent appointment.
Note: it is possible to have passed COVID-19 without developing antibodies. A small percentage of patients (around 2-5%) do not develop antibodies, probably having eliminated the virus through a cellular immune response.
