Blood Diagnostic Testing

For good reason, blood diagnostic testing is among the most common form of diagnostic testing. The smallest amounts of blood obtained for the test can assist your doctor in ruling in or out a variety of problems. Because of this, they are used for testing just about everything from common medical concerns to toxicology, blood screen tests, and everything in between. They are easy to have done and typically give very accurate results. 

Blood tests are typically the initial step in detecting dozens of illnesses, from diagnosing disease and infections to thyroid function to evaluating your cholesterol levels and other conditions. They are also very accurate for drug testing. A toxicology blood screen test can help determine if people are taking their medications properly and it can help determine if the correct dose has been prescribed which may be more appealing to p&s.

During a physical, checkup, or screening for a specific ailment, such as heart disease, thyroid disease, cancer, diabetes, or sexually transmitted diseases, your doctor will often request blood tests for you. Blood testing for medical providers is a large portion of what we do.

Why We Need Blood Diagnostic Testing

One of the most popular forms of lab tests is blood testing, generally known as blood work or labs. A blood diagnostic test is performed to quantify or examine the blood’s cells, molecules, proteins, or other components. Blood work is frequently performed as part of a routine checkup. Blood tests are also used to determine:

  • Whether your immune system is having difficulty battling infections.
  • Assist in the diagnosis of bleeding or clotting issues
  • Examine how well your organs are functioning. The organs in your body include your thyroid, heart, kidneys, and liver.
  • Determine whether a disease’s treatment is effective.
  • Maintain a close eye on chronic diseases or conditions, such as diabetes or high cholesterol.
  • Assist in the diagnosis of specific diseases and circumstances

Common Blood Testing for Medical Providers

Medical providers often have a series of blood tests that they will order on everyone. These are tests that give a good overall look at one’s health. However, blood tests are not limited to just these tests. Let’s look at some of the common blood testing for medical providers.

Complete Blood Count (CBC) – This test evaluates many components of your blood, such as hemoglobin, platelets, and red and white blood cells. A CBC is frequently included as part of a routine checkup. It can alert that an infection or that another disease process is occurring within the body. 

The Basic Metabolic Panel – This is a series of tests that assess the levels of several compounds in your blood, such as glucose, calcium, and electrolytes. It, again, is a good one to show a wide variety of issues within in test. Often a basic metabolic panel and CBC are ordered together.

Blood enzyme tests – Enzymes are proteins that regulate chemical reactions in your body. There are numerous blood enzyme assays available. This test determines whether you’ve had a heart attack and/or whether your heart muscle is damaged. It’s also tests for the thyroid and other tests that regulate iron for anemia.

Blood testing to detect heart disease –  These include cholesterol and triglyceride levels.

A coagulation panel –  A collection of blood clotting tests. These tests can determine whether you have a disease that causes excessive bleeding or clotting or monitor treatment for those.

Frequently Asked Questions About Blood Diagnostic Testing

Most blood tests do not require any preparation. Some exams may require you to fast (not eat or drink) for several hours before the test. Your health care provider will give you specific instructions. Be sure to follow those instructions to get the best possible results. 

Venipuncture is the most common way to collect blood. Collection takes place from a superficial vein in the upper limb, generally the median cubital vein; this vein is close to the skin and doesn’t have many large nerves close by. When the needle is put into the vein, you may feel a tiny prick. This is very common, and you should not feel uncomfortable at all during the procedure. If there is any pain from the venipuncture, please tell your phlebotomist immediately. There are two other ways to gather blood from a patient. These are a finger prick and a heel stick (performed on infants who are not yet walking), which is typically done in a hospital or doctors office.

Blood tests might reveal vital information about your health. However, it does not always provide sufficient information about your condition. If you’ve undergone blood testing, your provider may require additional tests, such as imaging, before making a diagnosis.

If you have had blood tests ordered by your medical provider, there is really nothing to worry about. Getting your blood drawn for the tests is relatively simple, safe, and pain-free. However, you may need to follow certain instructions given by your doctor, such as fasting. Be sure that you fully understand when you should have your blood drawn for the test as well. Some tests will need to be done first thing in the morning before you eat or drink. For others, it will not matter. Once your testing results are back, your doctor should follow up with you.
