XMRV Testing FactsThey forgot to put "Facts" in quotation marks.

What are some of the reasons that scientists looking for XMRV would fail to detect the virus in their patient samples?A bit no-no! Don't ever use a test on cells that don't contain XMRV! Better look first at the patient sheet belonging to the sample before testing – and add XMRV plasmid if necessary. Be careful though to add XMRV plasmid only to patient samples you need to be positive.
1) Use of a test on cells which don't contain XMRV
2) Use of a test which has not been clinically validated or proven that it can detect XMRV in a positive patient sampleThe WPI does not have a "clinically validated" test – because there is no such thing as validating "clinically" a test for a virus. Even if there were such a thing who validated this test for the WPI, when and how? Or did they "validate" themselves for themselves?
3) Use reagents not validated to detect XMRVThere is no rationale for validation of reagents with an unknown validation method. Even if it were done like the WPI says, then who validated the reagents for the WPI, when and how? Or did they "validate" themselves for themselves? And everybody should buy their "validated" reagents at the WPI?
5) Use of clinically validated tests on a patient sample that is truly negative for XMRVTruly negativ? There is no such thing, you always have false negatives at such a early stage.
And what the fuck happened to #4 ???? Got it shot in some lonely alley in Reno?
6)Testing patients which don’t satisfy rigorous clinical definition of XMRV such as is required in the Canadian Consensus Criteria.There is no "clinical" "definition" of XMRV. There never was. This is total fucking cuckoo woo. The Canadian Consensus Criteria (CCC) are a definition for the diagnose of CFS – claiming it is a definition for XMRV is getting it ass-backwards.
As illustrated above, there are many ways to produce false negative results.As illustrated above, there are many ways to disseminate false "facts" from a world of woo.
The failure to detect XMRV in a patient sample taken at one time, using one method, does not prove that a patient sample is negative for XMRV.Adding XMRV VP62 plasmid does not prove that a patient is positive for XMRV.
Why did WPI grant a license to a clinical laboratory (VIP Dx) to offer XMRV testing?As I have shown above, what you call "clinically" validated is nothing but woo – and so in the real world we live in (vs. the world of woo the WPI lives in) it turned out to be worthless expensive woo. And responsibility? What responsibility? The VIP Dx offered this bogus test for over a year and you didn't notice? I see no responsible behaviour by the WPI, only a world of woo.
1) WPI felt a responsibility to offer a clinically validated test to doctors who wanted to know if their patients were positive for XMRV, but only after another lab began offering a non-clinically validated blood spot test for XMRV.
2) Because VIP Dx is a locally operated CLIA certified laboratory, WPI can better assure quality control.WHAT FUCKING "QUALITY CONTROL"? The tests of the VIP Dx fell apart quite spectacular.
3) The non-exclusive license to VIP Dx supports the work of WPI.So you got money for this woo test? And you wanted to sell this woo-license to others?
Questions about the Science study.Yes, the science study is questionable.
Why did scientists have to use four methods to detect XMRV in the Science study to be absolutely sure that a sample was positive or negative for XMRV?Already the question is loaded to indicate the study was done to somehow higher standards to be somehow "absolute sure". What a piece
If one carefully studies the data presented in the Science paper one would see that patients can be negative by some methods and positive by others.Yes, it looks more legit this way and there are more ways to throw sand in the eyes of science.
Where did the patient samples used in the Science study come from?Yes, there were claims that more people in the study had cancer, or were diagnosed with cancer after the study.
Samples used in the study came from several medical practices and from patients who became ill while living in many different locations around the United States.
Did all of the samples come from patients who were physician-diagnosed with CFS?
Did any of the samples used in the original study come from patients who ultimately developed cancer?
How were the samples chosen?Why did only 101 patients out of these 200 patient samples end up in the study?
All of the patients/samples used in the study were chosen randomly on the basis of a CFS diagnosis from more than 200 patient samples stored in the WPI repository since 2006. No one knew the status of the patients as all samples were blinded. None of the samples came from the original repository of samples owned by Dr. Peterson.
What work was done after the May 2009 submission of the Science paper?
After the study was submitted, samples from CFS patients who also developed cancer were tested and found to be positive for XMRV. These results were reported at a private meeting of cancer researchers interested in XMRV. (A positive finding was not surprising, since retroviruses are known to cause cancer.).
These must have been the cancer patients people thought were in the Science study.
Similarly, samples from families with autism and CFS were tested and XMRV was detected in samples from autistic children.Surely these test were done unblinded by the head of lab, as in the Science study? Why wasn't there a follow-up study with larger sample sizes?
Research on immune defects in XMRV infected patients have also been studied and reported at scientific meetings.CFS research at the WPI, the gift that keeps on giving!
Can CFS patients develop serious complications after years of being ill?No kidding, studies need to be completed? At the rate your patients develop cancer, these will truly be amazing results.
Yes, doctors have reported that CFS patients have developed serious complications after being ill for many years, but a formal epidemiological study still needs to be completed.
Why is it important to do research on patients with a chronic disease who later develop complications from that illness?Unfortunately, this piece of
The mind puzzles why anybody believed anything that came from the WPI or their employees.
