About this profile
The DTX-03 Initial Testosterone Blood Test is designed as the first step in assessing testosterone levels before a consultation with a testosterone specialist.
This focused hormone blood test measures Total Testosterone, SHBG (Sex Hormone-Binding Globulin) and Albumin, providing important information to help assess your testosterone status and support the calculation and interpretation of free testosterone.
What does the DTX-03 test measure?
Total Testosterone
Measures the total amount of testosterone circulating in your blood. Testosterone plays an important role in male sexual health, energy, muscle strength, mood, bone health and general wellbeing.
SHBG – Sex Hormone-Binding Globulin
SHBG is a protein that binds to testosterone in the bloodstream. Measuring SHBG alongside total testosterone can provide a clearer understanding of how much testosterone may be available for the body to use.
Albumin
Albumin is another blood protein that binds to testosterone. When measured together with Total Testosterone and SHBG, albumin can help support the calculation of calculated free testosterone.
Why take this test?
The DTX-03 test may be suitable if you are experiencing symptoms that could be associated with low testosterone, including:
Reduced sex drive or libido
Erectile difficulties
Low energy or persistent fatigue
Reduced strength or muscle mass
Changes in mood or motivation
Difficulty concentrating
Reduced general wellbeing
It can also be used as an initial testosterone check before arranging a consultation with our testosterone specialist.
Why test Total Testosterone, SHBG and Albumin together?
Total testosterone alone does not always provide the complete picture. Testosterone circulates in the blood partly bound to proteins, particularly SHBG and albumin.
Measuring Total Testosterone, SHBG and Albumin together gives the specialist additional information to interpret your hormone levels and, where appropriate, calculate your estimated free testosterone.
When should I have the blood test?
For an initial assessment, testosterone blood samples are generally best taken in the morning, when testosterone levels are normally highest.
Where possible, we recommend having your sample taken before 11:00 am and following any preparation instructions provided when booking.
What happens after the test?
Once your blood results are available, they can be reviewed as part of your testosterone assessment.
If further clinical assessment is appropriate, you can arrange a consultation with our testosterone specialist, who can review your symptoms, medical history and blood results and advise whether any additional investigations are required.
The DTX-03 blood test alone does not diagnose testosterone deficiency and does not automatically mean testosterone replacement therapy (TRT) is required. Diagnosis and treatment decisions should be made following an appropriate clinical assessment.
