Readers continuously ask me where/how they can get tested for mycobacterium avium paratuberculosis (MAP) infection. This is a bacterial/fungal hybrid that hides inside your cells, so is only detectable if you test for the DNA or RNA of the organism. However, over 90% of Crohn’s patients carry MAP when tested in clinical trials.

And yes, Jini’s Wild Oregano Oil Protocol can eradicate MAP – when combined with holistic healing protocols (diet, emotional healing, bodywork, high dose probiotics, immune strengtheners and so on) – but for those who want solid proof that they either have it, or have eradicated it, they may want the DNA/RNA lab test.

There used to be a couple of labs (over the decades) that could do the test, but after a few years, they stopped or switched services. However, I’m very pleased to hear from Dr. J.E. Williams that there is a lab (that he recommends to all his patients) that can not only do the MAP test, but other tricky viral tests as well.

The lab is called Aperiomics and they have full instructions on their website for both patients and doctors:

“Aperiomics provides state of the art DNA testing for over 30,000 microbes of the viral, bacterial, parasitic and fungal variety. This is a powerful silver bullet in testing for any savvy physician to diagnose the underlying root causes of most medical illness from chronic fatigue to headaches to IBS and a variety of pain syndromes, just to name a few. The staff are friendly, approachable and responsive. It has made a significant difference in the care of my patients and has saved many lives.” – LH Zackrison MD

Another lab – recommended by a reader – that also looks good is Karius. They have a comprehensive list of all the pathogens they test for, with lots of data, research papers, etc.

Which lab is better?

I consulted with 2 friends of mine for their expert opinion on which lab they would use if they wanted to test for MAP. Friend #1 has a PhD in Immunology. Friend #2 is a Medical Geneticist. Here’s what they said:

Immunologist: “Assuming the purpose was to identify the cause of a systemic infection (as that appears to be primary utility for a clinician through whom the test is ordered), I’d choose Karius as, out of the two, it is the only one to have clinical and analytical validation – which they have published, provide limit of detection and are CLIA-certified. The other one, not so much.”

Medical Geneticist: “Karius is definitely the serious one of the two. One concern for your readers is the high false positive rate – it means they will need to get a follow up test to confirm any positive results. If they just want to rule out infection, it’s pretty good – that is, it has a low false negative rate.

Aperiomics is a microbiome company, meaning it will spit out everything in a sample, whether disease causing or not. That can be interesting but without validation studies you never know what their accuracy is.
