Should I Get A Home Finger Prick Test

I heard about celiac and I read some of the symptoms which really got me worried then I stopped having gluten for 2 days. I know evil bad. Slap myself on the wrist. So today I started eating it again and I wonder if the finger prick test will be accurate now. Do you think 2 days is fine. The test should still work? Also how accurate is it? I don't have money for a full blood test so if this comes out a strong positive, is that enough to assume I'm celiac?

I am not familiar with a finger prick test. Might not be available in the US? You might want to see if there are any reputable sites with info on it?

I doubt 2 days would really effect any test, especially if you ate gluten for a few days before the test.

Yeah I think I'll be fine. I'm not in the US. I'm in South Africa and we do have them

 

Edit: when I say fine I mean fine to take the test

I used the Biocard finger prick test and it worked for me. The Biocard test tests for normal levels of serum IgA (the control line) and elevated levels of tTG IgA (tissue transglutaminase) - if it is elevated there is a line.

 

When I did the test I had a very faint false positive line. I'm not sure if it was because I did not quite get enough blood into the test, but regardless it was a very faint line.  When I had the test re-run by a doctor, it was very positive, but I was also "gluten loading" by eating a LOT of gluten for a few weeks.

 

I would make sure you have eaten adequate amounts of gluten before you test. It may be better to wait a while and eat gluten heavy for a few days or weeks before testing (if you have been gluten light of gluten-free).

 

Good luck!

      Diagnosis and further testing Celiac

      By Redanafs · Posted

      Hi everyone. Back in 2022 I had blood work drawn for iga ext gliadin. Since then I’ve developed worse stomach issues and all other health issues. My doctor just said cut out gluten. He did no further testing. Please see my test results attached. I just need some direction cause I feel so ill and the stomach pain is becoming worse. Can this test show indications for other gastrointestinal diseases?

      Thank you. These were the results TTG ABS NUMERICAL: > 250.0 U/mL [< 14.99]  Really don’t understand the results!

      Does Dailymed.nlm.nih.gov site have filters for gluten?

      By Scott Adams · Posted

      Clearly from what you've said the info on Dailymed is much more up to date than the other site, which hasn't been updated since 2017. The fact that some companies might be repackaging drugs does not mean the info on the ingredients is not correct.

      To evaluate the TTG antibody result we’d need to know the normal range for that lab.  Labs don’t all use the same units.  However, based on any normal ranges that I’ve seen and the listed result being greater than a number rather than a specific number, I’d say yes, that is high! Higher than the range where the test can give a quantitative result. You got good advice not to change your diet yet.  If you went gluten free your intestines would start to heal, confusing any further testing,

      Scott is correct….Thank you for catching that!      Direct link for info  of fillers.    http://www.glutenfreedrugs.com/Excipients.htm Link is on 2nd page  of www.glutenfreedrugs.com   Site was started by a pharmacist (or 2) maybe 15-20 yrs ago with LAST updated in  2017.  This makes it’s Drug List so old that it’s no longer relevant. Companies & contacts, along with suppliers &  sources would need to be referenced, same amount effort  as starting with current data on DailyMed      That being said, Excipient List is still be relevant since major changes to product labeling occurred prior ’17.           List is the dictionary that sources the ‘foreign-to-us’ terms used on pharmaceutical labels, terms we need to rule out gluten.    Note on DailyMed INFO— When you look for a specific drug on DailyMed, notice that nearly all of companies (brands/labels) are flagged as a ‘Repackager’… This would seem to suggest the actual ‘pills’ are being mass produced by a limited number of wholesaler suppliers (esp for older meds out of  patent protection.).      If so, multiple repackager-get  bulk shipments  from same supplier will all  be selling identical meds —same formula/fillers. Others repackager-could be switching suppliers  frequently based on cost, or runs both gluten-free & non- items on same lines.  No way to know  without contacting company.     While some I know have  searched pharmacies chasing a specific brand, long-term  solution is to find (or teach) pharmacy staff who’s willing help.    When I got 1st Rx ~8 years ago, I went to Walgreens & said I needed gluten-free.  Walked  out when pharmacist said  ‘How am I supposed  to know…’  (ar least he as honest… ). Walmart pharmacists down the block were ‘No problem!’—Once, they wouldn’t release my Rx, still waiting on gluten-free status from a new supplier. Re: Timeliness of DailyMed info?   A serendipitous conversation with cousin in Mi was unexpectedly reassuring.  She works in office of Perrigo, major products of OTC meds (was 1st to add gluten-free labels).  I TOTALLY lucked out when I asked about her job: “TODAY I trained a new full-time employee to make entries to Daily Med.’  Task had grown to hours a day, time she needed for tasks that couldn’t be delegated….We can only hope majorities of companies are as  conscientious!   For the Newbies…. SOLE  purpose of  fillers (possible gluten) in meds is to  hold the active ingredients together in a doseable form.  Drugs  given by injection or as IV are always gluten-free!  (Sometimes drs can do antibiotics w/ one-time injection rather than 7-10 days of  pills .) Liquid meds (typically for kids)—still read labels, but  could be an a simpler option for some products…
