Blood test results, made possible by the taking of Blood tests, are one of the most important tools that your doctor uses in evaluating your health status. It is important to realize that your Blood test result may be outside of what is called the ‘normal range’ for many reasons. Blood tests, including various Blood chemistry and hematology ‘Blood tests’ offered by most test labs, represent an economical way by which quality information about a patient’s physical condition, at the time of the Blood testing, can be made available to the physician. These Blood test results, after review and interpretation by a qualified Blood professional, play an important part in an overall diagnosis. Blood test results are compared and measured in ‘normal ranges’ for a given population group. Low cost Blood tests, discount Blood testing and even free Blood tests are available and listed in your local community.

Because most Blood test reference ranges (often referred to as ‘normal’ ranges of Blood test results) are typically defined as the range of values of the median 95% of the healthy population, it is unlikely that a given Blood sample, even from a healthy patient, will show “normal” values for every Blood test taken. Therefore, caution should be exercised to prevent overreaction to mild abnormalities without the interpretation of those tests by your examining physician. Again, a Blood test, though important, is only a part of the final diagnosis of a health problem. Often, you can get your Blood tested at the Bloodmobile.
Most Blood tests fall within one of two categories: screening or diagnostic.
Screening Blood tests are used to try to detect a disease when there is little or no evidence that a person has a suspected disease. For example, measuring cholesterol levels helps to identify one of the risks of heart disease. These screening tests are performed on people who may show no symptoms of heart disease, as a tool for the physician to detect a potentially harmful and evolving condition. In order for screening tests to be the most useful they must be readily available, accurate, inexpensive, pose little risk, and cause little discomfort to the patient.

Diagnostic Blood tests are utilized when a specific disease is suspected to verify the presence and the severity of that disease, including allergies, HIV, AIDS, Hepatitis, cancer, etc.
What is a Blood test? Blood tests are an essential diagnostic tool. Blood is made up of different kinds of cells and contains other compounds, including various salts and certain proteins. Blood tests reveal details about these Blood cells and, Blood compounds, salts and proteins
The liquid portion of the tested Blood is plasma. When our Blood clots outside the body, the Blood cells and some of the proteins in Blood turn into a solid. The remaining liquid is called serum, which can be used in chemical tests and in other Blood tests to find out how the immune system fights diseases. Doctors take Blood samples and grow the organisms, found in Blood tests, that cause illness, to evaluate each, microscopically.
How is a Blood test carried performed? Blood samples taken for Blood testing can be taken either from a vein or from an artery. A few drops of Blood are needed, most of the time. It is often enough to take a small drop from the tip of your finger and then squeeze the Blood out for Blood testing. Most Blood tests are taken from a vein (veins carry Blood FROM the heart,) most often from those veins near the elbow. First a tourniquet is tied around the upper arm to make the vein easy to find and take the Blood for the Blood test.
The place where the injection is to take place is then made sterile and then a hollow needle is put into the vein. The needle will be attached either to a Blood test sample bottle or to a syringe where the plunger is pulled back to create low negative pressure. When the needed amount of Blood for testing has been removed from the vein, the needle is removed. The area is then re-cleaned and pressure is placed on the area with a small ball of cotton. This is pressed against the area for a couple of minutes before applying a bandage. Blood tests are relatively painless.
Platelet testing is a Blood test that is often used by doctors. First lets define platelets. Platelets are very small cells in the Blood. These clump together at places where injury to Blood vessels occur. They are the basis of the Blood clot that normally forms when the skin is broken.
A Blood test revealing a low platelet count can make us vulnerable to bleeding, sometimes even without an injury that we see. Some of the causes of a low Blood platelet count include autoimmune diseases, where the effected individual produces an antibody to his or her own platelets, chemotherapy, leukemia, viral infections and some medicines. High numbers of platelets make an individual more vulnerable to Blood clotting. High Blood platelet counts are always found where a condition involving bone marrow such as leukemia, cancer and other Blood borne conditions that are revealed by Blood test results.

No Blood test is completely accurate all of the time. Sometimes a test result is incorrectly abnormal in a person who does not have the suspected disease (a false-positive result). Sometimes a test result is incorrectly normal in a person who has the disease (a false-negative result). Tests are rated in terms of their sensitivity (the probability that their Blood testing results will be positive when a disease is present) and their specificity (the probability that their test results will be negative when a disease is not present). A very sensitive test is unlikely to miss the disease in people who have it, however, it may falsely indicate disease in healthy people. A very specific test is unlikely to indicate disease in healthy people. Although, it may miss the disease in some who have it. Problems with sensitivity and specificity can be largely overcome by using several different Blood tests.
Because your physician can not always be sure whether or not the reported result of a particular test from a particular person is false or true, a person with an abnormal result may often need to be re-tested or undergo a different type of testing.

Normal test result values are expressed as a reference range, which is based on the average values in a healthy population; 95% of healthy people have values within this range. These values vary somewhat among laboratories, due to methodology and even geography. Blood tests and Blood testing methods and quality vary widely in different parts of the world and in different parts of many countries, due to characteristics in the population, both racial Blood differences and ethnic Blood characteristics, among other factors.

American Blood laboratories use a different version of the metric system than does most of the rest of the world, which uses the Systeme Internationale (SI). In some cases translation between the two systems is easy, but the difference between the two is most pronounced in the measurement of chemical concentration. The American system generally uses mass per unit volume, while SI uses moles per unit volume. Since mass per mole varies with the molecular weight of the substance being analyzed, conversion between American and SI units requires many different conversion factors.
Keep in mind that there are three Blood test “normal ranges.”
Normal Range Results
The results of virtually all Blood tests ordered in North America are compared to “normal ranges” as provided on a “Lab Results Report.” If your tests indicate that you are within the normal range, you are most often considered normal. A “normal” Blood test result does not necessarily mean that you are healthy. The problem with these lies in how “normal ranges” are determined at that particular Blood testing laboratory.
Population Best/Optimum Ranges
In our opinion, every Blood test result must be compared to Blood test result scores other than the accepted lab “norms.” Your potential statistical best possible Blood test ranges must be considered. These Blood test range “best” results should interpreted considering your physiology and unique biochemistry such as your height your weight, age, gender, health history since childhood. Further, the inter-relationship with your other blood test scores must be considered. One imbalance often causes another. Blood test range scores outside your unique Blood test range results can be affected by sleep, diet, exercise, medicines, and vitamin supplements.

 

Your Personal Norms
Your Blood test score, chronicled over time, will vary by few points, one way or the other. These Blood test results, considering sleep, diet, exercise, medicines, and vitamin supplements, etc. will most certainly vary. Each person on any given day has their own set of Blood test results. Consider your gas mileage in your car. If reviewed over time, each time you fill up and record your gas mileage, it varies. The car is the same, the driver is the same, the gas is the same, but the mileage, from fill-up to fill-up varies. We recommend periodical Personal Blood Testing.Your personal norms must be considered over time. Each individual has his or her own unique personal Blood test normal range, best for you. Remember, if you do not get Blood tests, and if you do not keep track of them, and if you do not have them available to your doctor, You will not know and can not use your normal Blood test range.
