Full-length Gene Sequencing of Blood Leukocyte DNA (Whole Blood)

This test measures specific substances in your body, such as proteins, antibodies, hormones, or other markers, that can show how well certain organs are working or whether an infection, inflammation, or another condition may be present. Knowing exactly what is being measured can help you follow the conversation with your healthcare provider and understand what your results mean for your health.

The test examines the entire DNA sequence of your white blood cells, including all genes, to detect any full-length mutations. This includes checking for changes in genes that could be associated with inherited or acquired genetic disorders.

Your healthcare provider may order this test to help find the cause of symptoms you are having, to screen for a condition before it causes problems, to monitor an illness you already know about, or to check how well a treatment is working. It is often part of a routine checkup, but it may also be ordered for a more focused evaluation of a specific concern.

Your healthcare provider may recommend this test if you have symptoms suggestive of a genetic disorder, a family history of genetic conditions, or if certain genetic testing is suspected to be relevant to your diagnosis or treatment plan.

A small sample, such as blood, urine, or a swab, is collected by a trained member of our staff, and the process usually takes only a few minutes. Depending on the test, you may be asked to avoid food or certain drinks for several hours beforehand, hold specific medications, or drink extra water. You will receive clear instructions in advance, so follow them closely and ask questions if anything is unclear.

A blood sample is drawn from your arm. The white blood cells are isolated from the blood for genetic analysis. This process preserves the integrity of your DNA for accurate sequencing.

Your results are compared with established reference ranges, which reflect the values typically seen in healthy people. Your healthcare provider interprets your numbers in the context of your age, sex, medical history, symptoms, and current medications, because a value outside the usual range does not automatically mean something is wrong. Your provider will explain what your results mean and talk with you about any follow-up testing or next steps.

Results are reviewed by a genetic specialist who compares your DNA sequence to known genetic databases. They identify any full-length mutations that may require further clinical evaluation or management.
