What do your blood test results mean?| Trending Viral hub


your blood plays numerous roles to maintain your health. To carry out these functions, blood contains a multitude of components, including red blood cells that transport oxygen, nutrients and hormones; white blood cells that eliminate waste products and support the immune system; plasma that regulates temperature; and platelets that help with clotting.

Numerous molecules formed as byproducts of normal biochemical functions are also found within the blood. When these molecules indicate how your cells respond to disease, injury, or stress, scientists often refer to them as biological markers or biomarkers. Therefore, biomarkers in a blood sample can represent a snapshot of your body’s current biochemical state, and analyzing them can provide information about various aspects of your health.

As a toxicologist, Study the effects of drugs and environmental pollutants on human health. As part of my work, I rely on various health-related biomarkers, many of which are measured by conventional blood tests.

understanding that common blood tests are intended to measure can help you better interpret the results. If you have the results of a recent blood test on hand, follow us.

Blood samples go through several processing steps after they are drawn.


Normal ranges of blood rest

Depending on the laboratory that analyzed your sample, your blood test results can be divided into individual tests or collections of related tests called panels. The results of these panels can allow a healthcare professional to recommend preventative care, detect potential illnesses, and monitor current health conditions.

For each of the tests listed on your report, there will usually be a number corresponding to your test result and a reference range or interval. This range is essentially the upper and lower limits within which the test results of most healthy people are expected to fall.

Sometimes called the normal range, a reference interval is based on Statistic analysis testing of a large number of patients in a reference population. Normal levels of some biomarkers are expected to vary among a group of people, depending on their age, sex, ethnicity, and other attributes.

Therefore, separate reference populations are often created from people with a particular attribute. For example, a reference population could include all women or all children. A patient’s test value can then be appropriately compared to the results of the reference population that best fits them.

Reference intervals vary from one laboratory to another because each may use different test methods or reference populations. This means you may not be able to compare your results to reference ranges from other laboratories. To determine how your test results compare to the normal range, you should check the reference range listed on your lab report.

If you have results for a given test from different laboratories, your doctor will probably focus on the trends of the tests relative to their reference ranges and not on the numerical results themselves.

Interpreting your blood test results

There is numerous panels of blood intended to test specific aspects of your health. These include panels that analyze the cellular components of blood, biomarkers of kidney and liver function, and many more.

Instead of describing each panel, let’s look at a hypothetical case study that requires the use of multiple panels to diagnose a disease.

In this situation, a patient visits their healthcare provider for fatigue that has lasted for several months. Numerous factors and disorders. can cause prolonged or chronic fatigue.

Based on the physical examination, other symptoms, and medical history, the doctor suspects that the patient may be suffering from any of the following symptoms: anemia, underactive thyroid, or diabetes.

Blood tests would help further narrow down the cause of fatigue.

Anemia It is a condition that involves a reduced blood capacity to carry oxygen. This is due to lower than normal levels of red blood cells or a decrease in the quantity or quality of red blood cells. hemoglobinthe protein that allows these cells to transport oxygen.

TO complete blood count panel It measures various components of blood to provide a complete description of the cells that make up blood. Low values of the red blood cell count, or RBC, hemoglobin, or Hb, and hematocrit, or HCT, would indicate that the patient suffers from anemia.

hypothyroidism It is a disorder in which the thyroid gland does not produce enough thyroid hormones. These include thyroid-stimulating hormone, or TSH, which stimulates the thyroid gland to release two other hormones: triiodothyronine, or T3, and thyroxine, or T4. He thyroid function panel It measures the levels of these hormones to evaluate thyroid-related health.

Diabetes It is a disease that occurs when blood sugar levels are too high. Excess glucose molecules in the bloodstream can bind to hemoglobin and form what is called glycated hemoglobin or HbA1c. TO hemoglobin A1c test It measures the percentage of HbA1c present in relation to the total amount of hemoglobin. This provides a history of glucose levels in the bloodstream for a period of about three months before the test.

Providing additional information is the basic metabolic panel, or BMP, which measures the amount of various substances in the blood. These include:

  • Glucose, a type of sugar that provides energy to the body and brain. Relevant to diabetes, the BMP measures blood glucose levels at the time of testing.

  • Calcium, an essential mineral for the proper functioning of your nerves, muscles and heart.

  • Creatinine, a byproduct of muscle activity.

  • Blood urea nitrogen, or BUN, the amount of the waste product that the kidneys help remove from the blood. These indicate the state of a person’s metabolism, kidney health, and electrolyte balance.

Using the results from each of these panels, the healthcare professional would evaluate the patient’s values ​​in relation to their reference intervals and determine which condition the patient is most likely to have.

Understanding the purpose of blood tests and how to interpret them can help patients work with their healthcare providers and be more informed about their health.
