Should I be worried about abnormal blood test?

There's no magic about the cutoff point for calling a test result abnormal. Just as in the man with prostate cancer, a result in the normal range can still be a sign of disease. And results that are outside the normal range (“abnormal”) don't mean a person has a disease.

What does a blood chemistry test show?

They show how well certain organs are working and can help find abnormalities. Blood chemistry tests may also be called chemistry panels. There are many types of blood chemistry tests. They measure chemicals including enzymes, electrolytes, fats (also called lipids), hormones, sugars, proteins, vitamins and minerals.

What are lab values?

According to the Food and Drug Administration (FDA), normal lab test values are a set of upper and lower limits generally given as a range since normal values vary from person to person. Laboratory tests are commonly administered in discovering the cause of symptoms, confirming a diagnosis and screening for diseases.

What does L * a * b * stand for?

As shown below, L* indicates lightness, a* is the red/green coordinate, and b* is the yellow/blue coordinate.

How are normal lab values determined?

A reference range is usually defined as the set of values 95 percent of the normal population falls within (that is, 95% prediction interval). It is determined by collecting data from vast numbers of laboratory tests.

What do lab tests show?

Specifically, blood tests can help doctors: Evaluate how well organs—such as the kidneys, liver, thyroid, and heart—are working. Diagnose diseases and conditions such as cancer, HIV/AIDS, diabetes, anemia (uh-NEE-me-eh), and coronary heart disease. Find out whether you have risk factors for heart disease.

What can affect lab results?

Lots of things can affect certain lab test results, like:

  • Intense physical activity.
  • Some foods (like avocados, walnuts, and licorice)
  • Sunburn.
  • Colds or infections.
  • Having sex.
  • Some medications or drugs.

What does lab work include?

A typical routine blood test is the complete blood count, also called CBC, to count your red and white blood cells as well as measure your hemoglobin levels and other blood components. This test can uncover anemia, infection, and even cancer of the blood.

What does a full blood count show?

A complete blood count (CBC) is a blood test used to evaluate your overall health and detect a wide range of disorders, including anemia, infection and leukemia. A complete blood count test measures several components and features of your blood, including: Red blood cells, which carry oxygen.

What cancers cause high red blood cell count?

Polycythemia vera (PV) is a blood cancer that begins in the marrow of your bones, the soft center where new blood cells grow. It causes your marrow to make too many red blood cells so your blood is too thick.
