It details the period before and after symptom onset, highlighting the increasing probability of detection. The chart displays curves representing nasopharyngeal swab PCR, virus isolation from respiratory tract, bronchalveolar lavage/sputum PCR, stool PCR, IgM antibody, and IgG antibody detection. It indicates that PCR testing is likely positive in the early stages after symptom onset and can become negative later, while antibody detection becomes positive after symptom onset and remains detectable for a longer duration. The graphic also depicts the likelihood of detection over time, with nasopharyngeal swab PCR and virus isolation showing early high detectability, followed by stool PCR, and then antibody detection. The dashed lines for antibody detection show a prolonged presence of both IgM and IgG antibodies. This visual representation is crucial for understanding the optimal timing for different diagnostic tests in the context of COVID-19 infection, aiding in accurate diagnosis and management.",{"@graph":14,"@context":72},[15,34,55],{"@type":16,"itemListElement":17},"BreadcrumbList",[18,23,27,31],{"item":19,"name":20,"@type":21,"position":22},"https://docshare.wps.com","Home","ListItem",1,{"item":24,"name":25,"@type":21,"position":26},"https://docshare.wps.com/template/","Template",2,{"item":28,"name":29,"@type":21,"position":30},"https://docshare.wps.com/template/general/","General",3,{"item":32,"name":10,"@type":21,"position":33},"https://docshare.wps.com/template/timeline-of-sars-cov-2-diagnostic-detectability/194740/",4,{"url":32,"name":10,"@type":35,"image":36,"author":41,"headline":10,"publisher":44,"fileFormat":47,"inLanguage":8,"description":12,"dateModified":48,"datePublished":49,"encodingFormat":47,"isAccessibleForFree":50,"interactionStatistic":51},"DigitalDocument",{"url":37,"@type":38,"width":39,"height":40},"https://docshare.wps.com/thumbnails/timeline-of-sars-cov-2-diagnostic-detectability/194740.png","ImageObject",442,249,{"name":42,"@type":43},"Skyler","Person",{"url":19,"name":45,"@type":46},"DocShare","Organization","application/pdf","2026-09-29","2026-09-03",true,{"@type":52,"interactionType":53,"userInteractionCount":33},"InteractionCounter",{"@type":54},"ViewAction",{"@type":56,"mainEntity":57},"FAQPage",[58,64,68],{"name":59,"@type":60,"acceptedAnswer":61},"What is the purpose of this chart?","Question",{"text":62,"@type":63},"This chart illustrates the timeline of SARS-CoV-2 detectability using various diagnostic methods in relation to symptom onset, showing the probability of detection over time.","Answer",{"name":65,"@type":60,"acceptedAnswer":66},"When is PCR testing most likely to be positive for SARS-CoV-2?",{"text":67,"@type":63},"PCR testing for SARS-CoV-2 is most likely to be positive in the period shortly after symptom onset, with detectability peaking in the first week.",{"name":69,"@type":60,"acceptedAnswer":70},"How long can antibodies be detected after SARS-CoV-2 infection?",{"text":71,"@type":63},"IgM and IgG antibodies can be detected after symptom onset and typically remain detectable for several weeks, with IgG antibodies often persisting longer.","https://schema.org",{"og:url":32,"og:type":74,"og:title":10,"og:site_name":45,"og:description":12},"article",{"robots":76,"canonical":32},"index,follow",{"doc_id":78,"site_id":7},194740,1790055627,{"code":4,"msg":81,"data":82},"success",[83,88,93,98,103,108,113,118,123],{"id":84,"doc_module":22,"doc_module_name":25,"category_name":85,"show_sort_weight":86,"slug":87},11,"Presentations",90,"presentations",{"id":89,"doc_module":22,"doc_module_name":25,"category_name":90,"show_sort_weight":91,"slug":92},12,"Resumes",80,"resumes",{"id":94,"doc_module":22,"doc_module_name":25,"category_name":95,"show_sort_weight":96,"slug":97},14,"Invoices",70,"invoices",{"id":99,"doc_module":22,"doc_module_name":25,"category_name":100,"show_sort_weight":101,"slug":102},15,"Posters",60,"posters",{"id":104,"doc_module":22,"doc_module_name":25,"category_name":105,"show_sort_weight":106,"slug":107},16,"Social Media",50,"social-media",{"id":109,"doc_module":22,"doc_module_name":25,"category_name":110,"show_sort_weight":111,"slug":112},17,"Forms",40,"forms",{"id":114,"doc_module":22,"doc_module_name":25,"category_name":115,"show_sort_weight":116,"slug":117},18,"Letters",30,"letters",{"id":119,"doc_module":22,"doc_module_name":25,"category_name":120,"show_sort_weight":121,"slug":122},21,"Paper Templates",5,"papers-templates",{"id":124,"doc_module":22,"doc_module_name":25,"category_name":29,"show_sort_weight":4,"slug":125},158,"general-158",{"code":4,"msg":81,"data":127},{"doc_id":78,"user_id":128,"nickname":42,"user_avatar":129,"doc_module":22,"category_id":124,"category_name":29,"doc_title":10,"doc_description":12,"doc_content":11,"file_id":130,"file_url":131,"file_type":132,"file_size":133,"view_count":33,"is_deleted":4,"is_public":22,"is_downloadable":22,"audit_status":22,"page_count":134,"language":135,"language_code":8,"site_id":7,"html_lang":8,"table_of_contents":136,"faqs":137,"seo_title":138,"seo_description":12,"update_tm":139,"read_time":140},2336464648746,"https://ap-avatar.wpscdn.com/davatar_276721f389ce27ea32af1340a28f341c","cbCaifNqtI6plSaO","https://ap.wps.com/l/cbCaifNqtI6plSaO","pdf",577295,22,"English","# Diagnostic Detectability Timeline\n## Before Symptom Onset\n## After Symptom Onset\n### PCR -
