Navarro HCG Urine Immunoassay as a Cancer Diagnostic

The Navarro HCG test is a noninvasive urinalysis that can, with a high degree of accuracy, detect cell activity which may be indicative of a precancerous or cancer condition. The test has been used successfully for decades by many of our cancer patients to monitor their progress on a Biorepair/metabolic program. However, in order to benefit from this test, it is crucial that results are interpreted correctly. Limitations and nuances, some of which have emerged over the last 50 plus years as a result of Dr. Navarro’s experience with the test, must be clearly understood:

  1. The Navarro HCG does not detect what type of cancer may be present, nor is it a stand alone diagnostic for cancer screening. It is a quantitative measure of the body’s cell production activity which may be either in the normal or excessive range (abnormal cell production).
  2. You will receive a number in the form of International Units (I.U.) which indicates the amount of HCG in the sample. Studies have shown that below 50 I.U. is normal. If 50 I.U. or above – providing the subject is not producing excess cells because of pregnancy, stepped up tissue production due to burns or other physical damage, etc. – there is an imbalance and quite possibly a precancerous or cancerous state. According to Dr. Navarro, a positive result (50 I.U. or above) has proven to be over 95% accurate re: some kind of cancer activity – a very high degree of accuracy compared to more conventional diagnostics.
  3. It might seem logical that the higher the positive I.U. number, the greater the degree of excess cell production and, therefore, the greater concern for cancer activity. However, Dr. Navarro has recently informed us that there is not necessarily a direct relationship. In other words, some types and stages of cancer naturally read in very high numbers, while others in lower numbers, regardless of the degree of activity. Thus, some people who tested in consistently low positive numbers and, therefore, took no particular action, later discovered they had virulent disease.
  4. Because a single I.U. number cannot in itself show degree of activity, THE MOST IMPORTANT ASPECT OF HCG RESULTS IS THE DIRECTION OF NUMBERS IN SUCCESSIVE TESTS. If you have been diagnosed with cancer and wish to monitor the progress of your treatment program, it can be most helpful to take the test every few months: if the numbers go down, that is a good indication that you’re on the right track. If numbers go up as little as 1 point, Dr. Navarro advises, that would be cause for additional testing or, at least, tweaking of your program with a competent professional.
  5. If you don’t have a cancer diagnosis, but suspect a problem or simply want to get a baseline reading, you can use the HCG as part of a larger picture. A positive result can be compared with other tests, such as ultrasound, MRI, CEA, AFP, Ca 15-3, PSA, etc. Even if other tests are negative, since the HCG test has such a high degree of accuracy, i.e., small chance of false positives as far as some kind of cancer activity – possibly before any tumor or serious malignancy is present – the test can serve as an early warning device: you can assume some sort of imbalance and perhaps nip the problem in the bud by making lifestyle changes as needed, such as improved diet, increased moderate exercise, reduced stress, etc. Then retake the test in a few months.
  6. Because HCG is difficult to extract, the test has an 85% degree of accuracy for negative results (15% chance of false negatives) – still very low compared to other tests. (For example, the PSA has 40% chance of false negatives). So, if you receive a result in the mid-high 40’s I.U. range, you might consider retaking the test in a couple of months. The key factor is always the DIRECTION of the numbers in successive tests: if readings go down, you can be relatively confidant that what you’re doing is effective; if going up (as little as 1 point), some other intervention and/or testing may be called for.
