The lab is best known for its tick testing, which has been free to state residents since 2019, when a spike in Lyme disease prompted state legislators to fund the lab\u2019s work.\n<\/p>\n
Part of what\u2019s made it such an important service is the nature of tick-borne illnesses \u2014 and the tests available to catch them.\n<\/p>\n
\u201cThe pathogens that cause these diseases are really smart,\u201d Chinnici said. \u201cThey don\u2019t circulate in our blood system, so we can\u2019t just do a test like we do on the tick from your blood.\u201d\n<\/p>\n
Instead, human tests have to rely on the body\u2019s antibody response, which can take six to eight weeks to emerge. That presents a problem for treatment.\n <\/p>\n
\u201cWith Lyme disease and some of these other tick-borne illnesses, we know from researchers that you need to get treated within the first 30 days to have a really good battle against it and reduce the long-term symptoms that you may experience from it,\u201d Chinnici said.\n<\/p>\n
In fact, the official advice concerning Lyme disease \u2014 especially high-risk bites, which include bites by blacklegged ticks that are attached for 36 hours or longer \u2014 is to begin a course of antibiotics within 72 hours of removing the tick.\n<\/p>\n
But most people don\u2019t know what kind of tick they\u2019ve plucked off their bodies, or how long it was attached \u2014 which is where the Tick Research Lab comes in. Despite receiving hundreds, and sometimes upwards of a thousand, ticks in the mail every day, the lab manages to return results to most people within 36 hours.\n<\/p>\n
\u201cAnd that\u2019s really important because when we\u2019re talking about tick-borne illnesses, our goal is to get you results before you have symptoms,\u201d Chinnici said. \u201cSo if you have a tick that\u2019s attached to you and you\u2019re very concerned, I would priority ship that to us to speed that up.\u201d\n<\/p>\n
In addition to testing for pathogens, the lab provides tick identification, revealing which diseases it\u2019s most likely to harbor, as well as an estimate of how long the tick was feeding.\n<\/p>\n
\u201cSo a tick that\u2019s on you for 24 hours or more would mean a greater risk for a disease to have transmitted,\u201d Chinnici said. \u201cSo we look at the engorgement of the tick and then we test it for five different tick-borne illnesses.\u201d\n<\/p>\n
Those are the five most common \u2014 and dangerous \u2014 tick-borne illnesses in Pennsylvania: Lyme disease, Powassan virus, two forms of anaplasmosis, babesiosis and hard tick relapsing fever, or HTRF.\n<\/p>\n
The lab also offers two higher tiers of testing: the advanced panel ($50 for state residents) and the comprehensive diagnostic panel ($100 for state residents), which screen for dozens more tick-borne diseases that are rarer in Pennsylvania.

For anyone stuck on choosing a panel, Chinnici recommends starting with the basic, free option \u2014 and sending your tick off as soon as possible, since symptoms can take days or weeks to appear.\n<\/p>\n
\u201cIf you can find that tick bite \u2014 and you\u2019re lucky enough to have seen that, because not everyone will see a tick bite \u2014 you send that in for testing, and you can always start out with the basic panel tick testing and allow our researchers to give you an understanding of what that tick is, how engorged it was,\u201d she said. \u201cBecause if we send it back and tell you you\u2019ve been exposed to a blacklegged deer tick, but it was only on you for seven hours, even if that tick is carrying a tick-borne illness, most of the tick-borne illnesses take 24 hours to transmit.\u201d\n <\/p>\n","protected":false},"excerpt":{"rendered":"Why (fast) testing matters The lab is best known for its tick testing, which has been free to…\n","protected":false},"author":2,"featured_media":206168,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[6],"tags":[28,30,29,76344],"class_list":["post-206167","post","type-post","status-publish","format-standard","has-post-thumbnail","category-pennsylvania","tag-pennsylvania","tag-pennsylvania-headlines","tag-pennsylvania-news","tag-ticks"],"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/us-pa\/wp-json\/wp\/v2\/posts\/206167","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/us-pa\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/us-pa\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-pa\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-pa\/wp-json\/wp\/v2\/comments?post=206167"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/us-pa\/wp-json\/wp\/v2\/posts\/206167\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-pa\/wp-json\/wp\/v2\/media\/206168"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/us-pa\/wp-json\/wp\/v2\/media?parent=206167"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-pa\/wp-json\/wp\/v2\/categories?post=206167"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-pa\/wp-json\/wp\/v2\/tags?post=206167"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
