Lab Tests


Lab Tests are grossly inaccurate. You can use two different labs and get two different results. This information below is  meant to make you aware of the importance of preventative medicine so you do not have to rely on blood tests.  

According to Robert Mendelsohn, M.D. author of the book  “Confessions of a Medical ”  he writes

“Lab tests do more harm than good.  The medical laboratories are scandalously inaccurate.   The Center for Disease Control (CDC) reported that its survey of labs across the country demonstrated that ten to forty percent of their bacteriologic testing was unsatisfactory, thirty to fifty percent failed various simple clinical chemistry tests, twelve to eighteen percent flubbed blood grouping and typing and twenty percent botched hemoglobin ad serum electrolyte tests.  Overall, erroneous results were obtained in more than a quarter of all the tests.  In another nationwide survey, fifty percent of the “high standard” labs licensed for Medicare work failed to pass.  A large scale retesting of 25,000 analysis made by 225 New Jersey labs revealed that only twenty percent of them produced acceptable results more than ninety-nine percent of the time.  Only half passed the test seventy five percent of the time.

To get some idea of what people are really getting for their $12 billion worth of lab tests reach year, thirty-one percent of a group of labs tested by the CDC could not identify sickle cell anemia.  Another test group incorrectly identified specimens as indicating leukemia.  And from five to twelve percent could be counted on to find something wrong with specimens which were healthy!   My favorite study is one in which 197 out of 200 people were “cured” of their abnormalities simply by repeating their lab tests!

If you think these tests are shocking, keep in mind that the Center for Disease Control monitors and regulates fewer than ten percent of the country’s labs.  So there tests indicate the best work of the best labs.  With the rest you pay your money and you take your chances.  And you will pay more and more, because doctors practicing “just in case medicine” are ordering more and more laboratory tests.

As long as these tests have such an immense possibility for inaccuracy, the only way to look at them is as sacred oracles or fortune telling rituals.  Even if tests results are miraculously correct, there is still danger that the doctor will misinterpret them.

One woman wrote me that at her last routine examination, a test revealed blood in her stool.  Her doctor subjected her to every possible test, including barium x-rays, all of which proved negative.  The doctor did not give up.  Though the woman was in real pain because of the tests, he recommended further testing.  Six months later, his diagnosis was announced to a much weakened woman, she had too much acid in her stomach.

Lab tests and diagnostic machines wouldn’t be so dangerous if doctors were not addicted to the quantitative information these tools provide.

Whether the tools are simple, like thermometers, scales or calibrated infant bottles or complicated like x-ray machines, EKG’s EEG’s and lab tests, people and doctors are dazzled into crowding out of the process their own common sense and the qualitative judgment of doctors who are real diagnostic artists.”

Dr Robert Mendelsohn was a practicing pediatrician for 30 years.  He was known to millions through his nationally syndicated column as “The People’s Doctor” and was the national medical director of Project Head Start and Chairman of the Medical Licensing Committee for the State of Illinois.  Among the many faculty and hospital posts he held, he was an associate professor of Preventative Medicine and Community Health at the University of Illinois Medical School and a director of Chicago’s Michael Reese Hospital.  He has received numerous awards for excellence in medicine and medical instruction.
