Low testosterone levels or Hypogonadism is a disorder that mainly affects aging men. This when the testicular glands secrete insufficient levels of testosterone which, in turn, leads to the following debilitating symptoms in men:
- Low sex drive
- Sleep difficulties
- Excessive weight gain
- Loss of muscle mass and strength
- Loss of bone density
- Poor outlook on life
As we age, it’s normal for our bodies to produce less of the testosterone hormone, as well as all the other types of hormones. However, to know for sure if the levels of testosterone in our bodies have gone abnormally low, we need to undergo a lab test. Get a blood test for Low T by filling out our Quick Info Form. You can also call us at 888-663-1777 with your questions or concerns.
The Low T Test
A simple blood test panel is used by your Testosterone Therapy Doctor to check the testosterone hormone levels in your body. When the levels are low, your hormone treatment physician will prescribe a customized treatment plan to normalize your testosterone levels and get you back to optimum condition.
Many men who take testosterone, especially injections – experience a boost in their sex drive and frequency of sex, ability to build muscle and increase muscle strength, ability to burn fat and lose weight, an improved sense of well-being, a good mood, and renewed enthusiasm for daily living and their relationships.
Testosterone Therapy will boost your low testosterone levels back up into the normal range. An increase in your Free Testosterone or Bio-Available Testosterone will help restore your vitality, stamina and sexual desire.
Testosterone Test Preparation
No preparation is required before the test. Often, our Testosterone Treatment Physicians want the test to be done in the morning, when testosterone levels are highest. Although it is ideal to fast for 8 to 12 hours before a testosterone hormone test, there is no absolute requirement for 12 hour fasting prior to the test and our physicians will have your lab test results in 1 to 2 days. The blood test will check your Free Testosterone and Total Testosterone Levels. Keep in mind that testing only total testosterone levels is not as good an indicator for hormone deficiency as measuring your Free or Bio-available levels.
Testosterone Testing is used to Diagnose Hormone Health conditions in Men – Andropause, Hypogonadism, Erectile Dysfunction (Impotence)
Low T levels can be caused by pituitary or testicular functional problems, prescription drugs or medications, aging, andropause (male menopause), obesity, injury, ED or Erectile Dysfunction due to androgen deficiency. Endocrine physicians, urology doctors, age management and anti-aging medicine professionals will prescribe TRT or Testosterone Replacement Therapy to replace lost or low male sex hormone levels.
The lab tests used for diagnosing low t levels will provide blood serum results for the amount of androgen found in Total Serum Testosterone; Free Testosterone; Bioavailable Testosterone (Free androgens plus those loosely bound to blood plasma albumin); levels of SHBG (Sex Hormone Binding Globulin). There are basic hormone test panels and comprehensive hormone test panels that better help your treating physician get a more detailed result of your endocrine profile. Other tests include LH (Luteinizing Hormone) levels, FSH levels (Follicle-stimulating Hormone), Estradiol (estrogens), thyroid, red blood cell count, DHEA levels.

TTST – TTBS – TTFB – Lab Test Results
Types of Androgen Hormone Testing. There are three main types of testosterone test from a basic test to a more comprehensive measurement of all types of testosterone circulating in the blood:
- TTST – Testosterone, Total, Serum
- TTBS – Testosterone, Total and Bioavailable, Serum
- TTFB – Testosterone, Total, Bioavailable, and Free, Serum
Normal Testosterone Levels. Laboratories have reference ranges for what they consider normal testosterone hormone levels. In fact, what is considered a normal androgen level can vary from lab to lab and the expertise of your endocrine physician becomes invaluable in determining if the results of your blood test place you into a deficiency or borderline deficiency. The variations in lab test reference range for total androgen blood serum levels are apparent with many labs using 240-950 ng/dL in their lab test reports, and others with test result ranges from 300 to 1,000 or even 1,200 ng/dL. The main thing to keep in mind with regards to low t testing is that many men who have a near normal Total Serum Testosterone reference level can still exhibit symptoms of low testosterone because their Free Testosterone levels are low.
Free and Bio-Available Androgen Levels. The typical range for free blood serum testosterone is 9-30 ng/dL and bio-available blood serum 80 to 200 ng/dL. The androgens Free Testosterone and DHT (dihydrotestosterone) circulate in the blood plasma unbound or freely at about 2% to 4%. The bound androgens consist of specific protein bound (60%) and non-specific protein bound (36%) which accounts for the remaining 97% to 98%.
How are these remaining androgens bound? The remaining testosterone is bound to specific plasma proteins called SBHG or sex hormone-binding globulin and to nonspecific plasma proteins known as the albumin. The SHBG-bound androgens are biologically unavailable for use by a man’s body whereas those non-specific loosely bound to albumin are relatively bio-available. For male hormone replacement and testosterone optimization purposes, free testosterone which is entirely unbound and Bioavailable testosterone which is weakly bound are the most important measurements to consider.
