Yes, the testing is just as accurate. The DNA in a person's blood sample is the same as the DNA in a person's skin cells that are collected from inside the mouth. This sample is obtained by use of a soft cotton swab that is rubbed on the inside of the mouth (a "buccal swab").

Since DNA is the same in every cell of the human body, the accuracy of testing performed on cheek cells utilizing the Buccal Swab is the same as an actual blood sample. We believe this non-invasive and painless procedure is the best method for collecting a DNA sample.

A buccal swab is like a larger, more durable Q-Tip. It is rubbed against the inside cheek to gather loose cheek cells. It has become the standard sample collection method for DNA testing because it is safe and painless. DNA is the same in all cells of the body; thus test results are the same regardless of whether the sample is from buccal swabs or blood.

A buccal (Pronunciation ) swab is a specialized applicator with a sponge or Dacron tip, which is rubbed on the inside of the check to collect epithelial cells. This procedure is noninvasive and pain free.

A mouth swab looks like a long cotton wool bud. It is used to collect cheek cells from the inside of your mouth. DNA is consistent throughout the body, so the DNA in cheeks cells is identical to the DNA in blood cells. The mouth swab allows for non-invasive and painless collection of DNA. (top of page)

A nasal swab involves placing a swab inside the nostrils and taking a culture. The CDC and the U.S. Department of Health and Human Services do not recommend the use of nasal swab testing by clinicians to determine whether a person has been exposed to Bacillus anthracis, the bacteria responsible for anthrax, or as a means of diagnosing anthrax. At best, a positive result may be interpreted only to indicate exposure; a negative result does not exclude the possibility of exposure.

A blood test is more accurate, but it depends on the type you get. Many doctors will order a simple qualitative hCG. It only gives a yes or no answer, but doesn't register your HCG levels. If you are early in your pregnancy, and your levels are low, you may get a false negative. A quantitative blood test will measure the exact amount of hCG present. It will detect even the most minimal level.

All cells contain the same genetic material; hence results obtained by buccal swab samples are just as accurate as using blood.

Yes. In a multicenter clinical study this test service, using blood from a finger stick obtained by non-medically trained participants, was proven to be greater than 99% accurate compared to a blood sample drawn by a medical professional and tested using current test methods. In this clinical trial approximately 4% of study participants were unable to collect enough sample to begin testing, and an additional 3% were unable to collect enough sample to receive a conclusive result.

No, DNA test results are the same because the DNA is the same in all nucleated cells of a person's body. We use the most readily available source of DNA for paternity testing. The DNA we use is located inside the mouth, buccal cells. Every cell in body, except for red blood cells, contains the same DNA. Red bloods do not contain DNA. All DNA containing cells, including cells from buccal swabs, hair follicles and urine specimens, are suitable specimens for DNA analysis (1-3).

No. Read the first chapter in my book to learn how to test yourself, simply and accurately. All you need is a thermometer. Free access is available to this chapter on the right hand side of this page.

Our laboratory has a forensics testing division which specializes in forensic testing. Forensic samples which can be tested include but are not limited to: blood stains, saliva stains, hair with roots, bone, teeth, urine, razor shavings, etc. Click on this link to read more about our forensic testing services.

Genetic Professionals’ DNA paternity test is fast, simple, and painless. DNA is collected using special swabs that are like cotton tips. Gently rub the inner cheek with the swab to collect DNA samples. Buccal swabs are painless and can be used to collect samples from individuals at any age, even newborns. Yes, we can send our DNA collection kits to all tested parties at different locations if an in-home paternity test is ordered from Genetic Professionals.

The Q.E.D.? test can be used as an accurate screen in place of blood or breath tests. In clinical trials, saliva alcohol levels measured by the Q.E.D.? demonstrated high correlation to blood analyzed by gas chromatography (r=0.98).

Yes. The VAP Test is based on ultracentrifugation, the gold standard for reference lab lipid measurement. The test is processed at Atherotech's CLIA-approved diagnostic laboratory. In addition, Atherotech has the accuracy of the VAP Test confirmed by three highly recognized lipid standardization programs-the American Association of Bioanalysts, the Northwest Lipid Research Laboratories, and the Accutest Proficiency Testing Program.

The OptiGen direct mutation tests are exactly accurate. This means that the test gives clear readings in the laboratory; there is no issue of interpreting what we see. Numerous controls--absolute measures of accuracy--are used with every sample we process. The results for each dog will never change with age and will be the same whenever the same version of the test is repeated.

A single Aminomics blood test will provide information about the current status of your blood plasma. The re-interpretation of blood testing in response to treatment over-time guides us on our efficacy.

Blood pressure machines in large stores are okay for screening purposes and are usually fairly accurate, however, if your blood pressure reads high you should have it checked by your physician to be sure of the accuracy.

Answer : We test using serum. Testing serum verses whole blood gives us the advantage maintaining the specimen for a longer period of time, and more accurate results.

Single chemistry tests (Cholesterol, HDL, LDL, Triglycerides, Glucose, and Ketone), require 15 µL of whole blood. Lipid Panel tests require 35-40 µL of whole blood. Chol+Glu test panels require 25-30 µL of whole blood. Creatinine tests require 20 µL of whole blood. top
