Low energy. Slower workouts. Brain fog. Mood changes. Poor sleep. Low libido.
These problems often get blamed on aging or stress. Sometimes that’s true. Sometimes your hormones are the issue.
Testosterone affects strength, mood, focus, metabolism, and sex drive. When it drops, you feel it.
Testing is simple, fast, and affordable. Here’s how to do it step by step.
TL;DR: Quick Summary
The most accurate way to test testosterone is a morning blood test between 7 and 10 AM that checks total and free testosterone. You can test through your doctor, a walk-in lab like Quest or Labcorp, or an at-home finger-prick kit. Sleep well, avoid hard workouts and alcohol the day before, and test early in the day. If results are low, repeat the test to confirm before starting treatment.

What Is a Testosterone Test?
A testosterone test measures how much testosterone is in your blood.
Doctors usually check:
Total Testosterone
All testosterone in your bloodstream.
Free Testosterone
The portion your body can actually use.
Sometimes they also check:
- SHBG (Sex Hormone Binding Globulin)
- Estradiol
- LH and FSH (Luteinizing Hormone and Follicle-Stimulating Hormone)
These help explain why levels may be low.
For most people, total and free testosterone are enough to start.
Signs You Should Test Your Testosterone
You do not need severe symptoms to justify testing. If you feel off for several months, it is reasonable to check.
Common Symptoms in Men
- Low sex drive
- Erectile issues
- Ongoing fatigue
- Loss of muscle

How to Test Testosterone Levels
There are three main ways to do it. Pick the one that fits your schedule and budget.
Option 1: Doctor or Clinic Blood Test
Best for: Medical guidance and insurance coverage.
Steps:
- Schedule an appointment
- Get blood drawn in the morning
- Review results with your provider
✓ Pros:

If you already have a primary care doctor, this is often the easiest route.
Option 2: Walk-In Lab Testing
Best for: Speed and convenience.
You can order online and visit a lab the same day or next day.
Steps:
- Purchase the test online
- Visit a nearby lab (Quest, Labcorp, etc.)
- Get digital results
✓ Pros:
- No doctor visit needed
- Fast turnaround
- Accurate blood testing
✗ Cons:

This option balances convenience and reliability.
Option 3: At-Home Testosterone Test Kits
Best for: Privacy and comfort.
Steps:
- Collect a finger-prick or saliva sample
- Mail it in
- Receive results online
✓ Pros:
- Done at home
- Private

✗ Cons:
- Slightly less accurate than a standard blood draw
- Slower turnaround
These are fine for screening. If results are low, confirm with a lab test.
Types of Testosterone Tests Explained
Not all tests give the same information.
| Test Type | What It Includes |
|---|---|
| Basic | Total testosterone |
| Better | Total and free testosterone |
| Full Hormone Panel | Total testosterone, Free testosterone, SHBG, Estradiol, LH and FSH |
If you are considering treatment, the full panel gives a clearer picture.
How to Prepare for a Testosterone Test
Preparation affects your numbers more than most people think.
✓ Do This
- Test between 7 and 10 AM
- Sleep well the night before
- Drink water
- Eat normally unless told to fast
✗ Avoid This
- Hard workouts the day before
- Alcohol
- Poor sleep
- Testing late in the day
⚠️ Important: Testosterone can drop 20 to 30 percent by afternoon. Morning testing is more consistent.
What Happens During the Test?
Blood Test
A small needle draws blood from your arm. It takes about five minutes.
At-Home Kit
You prick your finger or collect saliva and mail the sample.
Both methods are low risk and quick.
Understanding Your Testosterone Results
Numbers need context.
| Category | Range |
|---|---|
| Adult Males (Normal Range) | 300 to 1,000 ng/dL |
| Adult Females (Normal Range) | 15 to 70 ng/dL |
General Guide for Men
- 600 to 900 ng/dL: Strong
- 400 to 600 ng/dL: Average
- 300 to 400 ng/dL: Borderline
- Under 300 ng/dL: Low
💡 Remember: Symptoms matter as much as the number. Some people feel fine at 400 ng/dL. Others feel tired at 350 ng/dL.
Doctors often repeat testing on two different mornings before diagnosing low testosterone.
What To Do If Your Testosterone Is Low
Do not rush into treatment. Start with basics first.
Step 1: Fix Lifestyle Factors
These changes can raise levels naturally:
- Sleep 7 to 9 hours
- Lift weights regularly
- Lose excess body fat
- Eat enough protein
- Reduce stress
- Limit alcohol
Step 2: Consider Simple Supplements
Some people benefit from:
- Vitamin D
- Zinc
- Magnesium
Think of these as support, not cures.
Step 3: Talk to a Provider About TRT
If levels stay low and symptoms continue, testosterone replacement therapy may be an option. Work with a qualified provider.
