Tips & Advice
How accurate are blood test results?
Blood tests offer a high degree of accuracy, but it's important to note that this might be compromised by issues that concern patient compliance and the lab that's handling the test results. For some tests, protocols such as fasting need to be observed prior to the test, and if not followed , it can compromise the test results. Also, bloodwork needs to be carefully handled by the lab to avoid contaminating or mixing up samples.
Are blood test results confidential?
Blood test results are confidential. If blood is being tested via an online lab, there is an option of using an alias to preserve anonymity. Confidential blood tests can be used to test for several things, including allergies, cancer, diabetes, drugs and alcohol, heart health, sexually transmitted diseases, blood disorders, and infectious diseases.
How much does a blood test cost?
Without health insurance, blood tests can cost $300-$1,200 or more. The total cost of having blood tests performed depends on the number of tests being done, as well as the type of blood tests being performed. With health insurance, out-of-pocket costs for a blood test may be limited to a $30 copay.
Does insurance pay for blood tests?
Insurance might pay for blood tests if the test has been requested by a doctor. If you want to make sure that the test is covered, check that the lab that is handling the test is part of your insurance network. Even though a doctor may recommend a lab that's outside your network, there is always the option of choosing an in-network lab facility.
Do all blood tests require fasting?
Not all blood tests require fasting, but fasting is necessary to get accurate results when having certain types of blood tests performed. With a blood glucose test--which is used to detect diabetes--you shouldn't consume anything but water in the eight to 10 hours preceding the test. With blood cholesterol tests, you will be asked to abstain from all food and drink except water in the nine to 12 hours preceding the test. A doctor or lab let you know if the test you are taking requires fasting.
How long does it take to get the results of a blood test?
For most types of blood tests, it takes about 24 hours to get results from the lab after the sample has been received. If the blood test has been ordered by a doctor, the results will usually be sent directly to the doctor's office.
How long does it take to do a blood test?
The actual process of having blood drawn for a blood test takes less than 3 minutes. Blood can be taken from a vein in your arm using a needle, and it can also be drawn by pricking your finger. A band is usually tied around the upper part of the arm just prior to this procedure which causes the veins to become more prominent. This makes it easier for the person drawing the blood to insert the needle.
What type of information is included in a blood test?
Blood tests can be used to measure full blood count, blood sugar level, inflammation, blood cholesterol level, antibodies to viruses and germs, blood clotting, blood grouping, and thyroid function. Blood tests can also be used to evaluate the function of liver and kidneys, which is especially important if you're taking prescription drugs that affect those functions.
When does a blood test become necessary?
Blood tests are used to diagnose certain diseases. If a doctor suspects you have one of these diseases, a blood test will be necessary to evaluate your condition. Blood tests are used to screen for health conditions and illnesses like anemia. Blood tests are also be used to evaluate liver and kidney function, as well as risk for heart disease.
Can patients request their own blood test?
As part of a federal law enacted a couple of years ago, patients can request a blood test from a lab without a doctor's note, but the costs of the test won't necessarily be covered by your health insurance. To get a blood test, you can go to a walk-in lab or visit the lab's web site and order the test online.
