You are missing some critical blood markers such as testing Free Testosterone using an accurate assay (ED or UF), SHBG, and LH/FSH.
Your TT was tested using the most accurate assay (LC/MS-MS).
Although TT is important to know FT is what truly matters as it is the active unbound fraction of testosterone responsible for the positive effects.
When it comes to testing FT it is critical to use an accurate assay such as the gold standard Equilibrium Dialysis or Ultrafiltration (next best), especially in cases of altered SHBG.
Keep in mind that men can have what would be considered healthy/higher-end TT and still have subpar FT due to high SHBG.
When Binding Proteins Interfere With Immunoassays
WHAT CAN BE DONE TO ENSURE ACCURATE LABORATORY RESULTS FOR THESE PATIENTS?
There are several strategies that both clinical and laboratory teams can take to ensure accurate measurements for patients with abnormal levels of binding proteins. Initially, if laboratory measurements do not agree with the clinical presentation of the patient, the analyte-specific binding globulin can be measured to rule out bias due to abnormal concentrations of binding proteins. If possible, the sample can be analyzed by the gold standard method, LC-MS/MS, which removes binding proteins by precipitation or, in the case of FREE HORMONE measurements, physically separates the bound from the free fraction via EQUILIBRIUM DIALYSIS or ULTRACENTRIFUGATION.
If measurement by LC-MS/MS is not feasible, the clinical and laboratory teams can collaborate to define appropriate reference intervals for specific patient populations.

Testosterone, Total, LC/MS and Free (Equilibrium Dialysis)
When it comes to testing FT any one of these would suffice:

Testosterone, Total, LC/MS, and Free (Equilibrium Dialysis)
Methodology: Free: equilibrium dialysis; total: liquid chromatography/tandem mass spectrometry (LC/MS-MS)
Another thing that stands out is you did not have your bloodwork done in a fasted state in the early am.
You never fasted and had blood drawn in the early afternoon at 2:10 pm.

Natural endogenous testosterone secretion is pulsatile and diurnal (24 hr circadian rhythm).
Testing should be done in a fasted state between 7-10 am as we want to test at peak.
*Testosterone levels decline after a meal or glucose
I would go for bloodwork between 7-8 am.
Blood work should never be done in the late afternoon/early evening when levels will be lower as nadir (lowest point) would be around 6-8 pm.
Fluctuations from peak--->trough would be around 20-25%.

What led you to have your hormones checked as you never stated that you might be experiencing symptoms of low T?
Would not jump to any conclusions until you have your FT tested using an accurate assay!
