What Laboratory Consultants Wish You Knew About Blood Tests
A comprehensive review of your blood test findings can help you make sound dietary and lifestyle choices. Standard blood tests ensure that CBC chemistry and cholesterol levels are within normal ranges. However, your doctor's office may fail to contact you about your findings or they could send you a copy without an explanation. Unlike general practitioners who conceal the reality of blood tests, a legitimate laboratory consultant would rather you know a few critical details.
Negative Tests Can Truly Equal Positive Results
Not all results are factual or biologically accurate. For example, blood tests for sickle cell anemia, HIV, hepatitis C, and breast cancer search for biomarkers in your blood sample to diagnose illnesses. When the test detects the infectious marker, the result is "positive." Therefore, it implies that you may have a disease or contagious virus in such a case.
Test Values Can Differ Depending on the Lab
Typically, a laboratory consultant oversees an operation that compares your blood test results to a generally normal range. The standard method depends on findings from a wide range of previous test patients at the facility. The chosen average level may not be the same as another in another lab. Therefore, if a prior blood test report contrasts with recent findings, the difference may depend on the particular facility. Also, you may have to consider finding a smaller location.
False-Positive Test Results Are Possible
Determining the first screening test findings for a condition is critical to your health. However, false-positive results are frequently validated by a second, more specialized test administered by a laboratory consultant. For example, an HIV test is often accurate but rarely results in a false positive. The issue can also occur with some antibody tests due to a conflict with an autoimmune disorder.
Improper Testing Can Compromise Results
While blood test mix-ups are uncommon, they do occur. How your blood sample is handled before an examination could also impact the results. For example, an incorrect result is possible if the sample is in the wrong container, shaken incorrectly, or retained for too long at the wrong temperature. If you want to know about the proper test management, ask a knowledgeable laboratory consultant.
While blood tests do not need any specific preparation, it would be best to maintain an empty stomach for eight to 12 hours before your test. Consult with your physician about how to prepare in advance.
