In the vast majority of my patients, I check a genetic test called an HLA DR/DQ from Labcorp (test #012542)    I learned about this test from Dr. Ritchie Shoemaker.   This gene is located on chromosome number 6 and it encodes a protein called an MHC Class II protein.   Each person has two copies: one from the father and one from the mother.   This test tells me if a person is susceptible to biotoxin illnesses and I’ve found that 98% of my patients are.
To give some background on this gene, when the immune system first encounters a foreign object such as a bacteria, the first immune cells to arrive on the scene are called APCs (Antigen Presenting Cells).  The APC  “eats” the foreign object then attaches it to a MHC Class II protein.   It’s like taking a piece of the bacteria and and putting it in a picture frame.   The APC then moves the foreign object and the MHC protein (the picture frame) to the surface of the cell so that the rest of the immune system (specifically T- cells) can study and learn how to defend against the foreign object.  The APC essentially tells the rest of the immune system, “Look what I found!  I put it in a picture frame!”
As an analogy, imagine that a crime was committed.    The first police officer on the scene was able to take a picture of the criminal before he ran away.  The policeman then shows a picture of the suspect to the rest of the police force.  The MHC  II protein does the same thing as the first police officer: to show a picture of the suspect to the rest of the immune system.
What if the police officer’s camera didn’t work well or he had trouble developing the picture?  He wouldn’t be able to show the picture to the rest of the police department so they wouldn’t know who to look for.  The cri...

...!   Another way of putting it is  nearly all of my patients come from only 25% of the population.  I have spoken to my colleagues across the country and they’ve had very similar findings to mine.  I sometimes joke that the HLA DR/DQ gene predicts if someone will get frustrated with conventional medicine and seek out alternative care.
I’ve written about some of the symptoms and diseases that are associated with these genes in my previous post. Unfortunately, there are only several hundred doctors in the world who  are aware of this gene. Therefore, the vast majority of doctors know nothing about this gene  so that countless patients are not diagnosed properly.  I suspect there has been an increase in the number of doctors who are aware of this gene as a result of a talk given at this year’s ILADS conference and hopefully this important knowledge will continue to grow.

How Standardized Tests Do Not Measure How Much A Child Has Learned Essay

- "A typical student takes 112 mandated standardized tests between pre-kindergarten classes and 12th grade" (Layton). This shocking statistic points to the shortcoming in the American education system. An education should be comprised of an array activities that foster an curiosity and excitement for learning. Learning by definition is, "the activity or process of gaining knowledge or skill by studying, practicing, being taught, or experiencing something" ("Learning").

Should Students Required A Bad Test Score? Essay

- Most states in the United States use standardized testing and testing in general, to assess the knowledge of their student and the quality of the teachers in schools.

Does this show that parents are starting to realize how unfair these tests are.
