Be In The Know About Testosterone Testing

What Should I Know About Testosterone Testing?

Wondering what your testosterone levels are? Now your doctor can measure the levels of testosterone in your bloodstream. Testosterone exists in males and females, but in males it is an essential sex hormone that drives secondary sex characteristics like muscle development, sperm production, and voice deepening. It is important to note that there are two types of testosterone in the blood—bound testosterone and free testosterone. Bound testosterone binds to proteins like the sex hormone-binding globulin (SHBG) or albumin, and free testosterone is unattached.

What is a Testosterone Test?

A testosterone test can let your doctor know if you have too much or too little of the hormone in your blood, which can help point to a primary cause if you are experiencing problems. Fortunately, there are two types of testosterone tests for measuring free testosterone and also for measuring total testosterone, which is the bound and the free testosterone together.

For your reference, the most recent research has shown that the normal T range for morning testosterone in men is 300-1,000 ng/dL. However, many factors influence the final result, including whether it is drawn in the morning or at night, age, other medical conditions, and stress levels.

The American Urology Association has indicated that a reading of 300ng/dL is low, but some other reference ranges go as low as 264ng/dL.

In women, normal testosterone levels are markedly lower, and according to the Centers for Disease Control and Prevention (CDC), a normal range is between 8-49ng/dL.

How Do They Work?

The blood test for measuring testosterone levels is usually drawn in the morning. Your doctor will want to do a physical exam, and will ask you about your medical history and any medications you are taking in order to take that into account when assessing you. If you are on hormone supplements or prescriptions, your doctor may want you to stop taking them before your blood test.

At-Home Testing

There are several different saliva test kits that will test your testosterone at home, although experts are unsure how accurate and reliable these kits are. According to the Human Kinetics Journals, these tests are unable to be as fast or accurate as blood tests. If you get an abnormal reading on a home testosterone test, you should consult your doctor for further testing/diagnosis/treatment.

Why Should I Test My Testosterone Levels?

A testosterone test can be a useful diagnostic tool to aid your doctor in diagnosing any of the following conditions:

  • Hypothalamus problems
  • Erectile Dysfunction (ED)
  • Early or late-onset puberty
  • Abnormal weight gain
  • Hot flashes
  • Low energy levels
  • Infertility
  • Excessive body hair growth

What are the Symptoms of Low Testosterone?

  • Decreased sex drive
  • Tiredness/fatigue
  • Early hair loss

Are There Treatments for Low Testosterone?

Fortunately, there are a number of treatment options for men with low testosterone levels, including topical gels, patches, and injections that contain testosterone. The Food and Drug Administration has limitations on approved uses for products containing testosterone, but your doctor will be familiar with these. In a review in BMJ Open, men using testosterone replacement therapies reported an improved quality of life, an improved libido, and an improvemnt in ED.
