Antigen and PCR tests confirm active infections, while antibody tests assess past infections and immunity. Choosing the right test at the right time ensures accurate results and informed health decisions. If you suspect a COVID-19 infection or need testing for travel or work, consult a healthcare provider to determine the best test for your situation.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-0a2c62e elementor-widget elementor-widget-marity_core_separator\" data-id=\"0a2c62e\" data-element_type=\"widget\" data-widget_type=\"marity_core_separator.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<div class=\"qodef-shortcode qodef-m  qodef-separator clear  qodef-separator-glow--no\">\n\t<div class=\"qodef-m-line\" ><\/div>\n<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-3895314 elementor-widget elementor-widget-text-editor\" data-id=\"3895314\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<h3>Literatuur<\/h3><ol class=\"innerList defaultList\"><li><a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/32340216\/\" target=\"_blank\" rel=\"noopener\">Optimal Nutritional Status for a Well-Functioning Immune System Is an Important Factor to Protect against Viral Infections<\/a><\/li><li><a href=\"https:\/\/www.nrc.nl\/nieuws\/2020\/09\/10\/geen-corona-toch-in-quarantaine-a4011600\" target=\"_blank\" rel=\"noopener\">https:\/\/www.nrc.nl\/nieuws\/2020\/09\/10\/geen-corona-toch-in-quarantaine-a4011600<\/a><\/li><\/ol>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-b20c09d elementor-widget elementor-widget-marity_core_separator\" data-id=\"b20c09d\" data-element_type=\"widget\" data-widget_type=\"marity_core_separator.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<div class=\"qodef-shortcode qodef-m  qodef-separator clear  qodef-separator-glow--no\">\n\t<div class=\"qodef-m-line\" ><\/div>\n<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>","protected":false},"excerpt":{"rendered":"<p>COVID-19 testing plays a crucial role in detecting infections, monitoring immune responses, and helping individuals make informed health decisions.
