Hi there<\/p>\n

Thanks for highlighting this.<\/p>\n

You are right that a few cases have been reported of people with COVID who have tested false positive for HIV. I have included links to the BMJ papers below.<\/p>\n

The false positive HIV results were only on the initial antibody tests, becasue of\u00a0the limitations of these tests.<\/p>\n

Any positive result on these tests always needs to be confirmed by laboratory testing, either using ELIZA or PCR tests. In all these published cases, the confirmatory tests were negative. In practice, this would apply to the small percentage of people who can test false positive to HIV antigen tests.<\/p>\n

It is still really important though for anyone hospitalised with COVID to know their HIV status, and to have an HIV test if they don’t know their recent HIV status.<\/p>\n

This is because the overlapping symptoms of COVID and some advanced HIV complications can be misdiagnosed as one rather than the other. Different treatment and management is needed for each situation.<\/p>\n

Unfortunately, there were cases of HIV symptoms being misdiagnosed as COVID which had very serious outcomes.<\/p>\n

I read online in the British Medical Journal that HIV has been misdiagnosed on people who have presented at A&E with fever and flu like symptoms. They tested positive for both Covid and HIV. <\/p>\n

When their Covid PCR result eventually came back negative so did their HIV. How common is this and what is put in place to ensure those who take a HIV test whilst in an active Covid infection receive the correct diagnosis? <\/p>\n","protected":false},"author":2,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[7,13,54,22],"tags":[],"class_list":["post-20864","post","type-post","status-publish","format-standard","hentry","category-all-topics","category-complications-and-coinfections","category-covid-19","category-hiv-testing"],"_links":{"self":[{"href":"https:\/\/i-base.info\/qa\/wp-json\/wp\/v2\/posts\/20864","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/i-base.info\/qa\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/i-base.info\/qa\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/i-base.info\/qa\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/i-base.info\/qa\/wp-json\/wp\/v2\/comments?post=20864"}],"version-history":[{"count":3,"href":"https:\/\/i-base.info\/qa\/wp-json\/wp\/v2\/posts\/20864\/revisions"}],"predecessor-version":[{"id":20867,"href":"https:\/\/i-base.info\/qa\/wp-json\/wp\/v2\/posts\/20864\/revisions\/20867"}],"wp:attachment":[{"href":"https:\/\/i-base.info\/qa\/wp-json\/wp\/v2\/media?parent=20864"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/i-base.info\/qa\/wp-json\/wp\/v2\/categories?post=20864"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/i-base.info\/qa\/wp-json\/wp\/v2\/tags?post=20864"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
