Preparing for a Total Testosterone Testing in Mentone, CA starts with three questions: whether you need to fast, when to collect, and what to bring. Total Testosterone Testing is a blood test that measures your overall testosterone level to see whether it is too high or too low.
What this test looks at
This test measures total testosterone, meaning the overall amount of the hormone present in the blood. Results are compared against a reference range to identify levels that are too high or too low. Your clinician interprets the number alongside your symptoms and history.
- Total testosterone
- Low total testosterone
- High total testosterone
Getting ready for the Total Testosterone Testing
Usually there is nothing out of the ordinary to do before this test. Ask the collection site about any timing or fasting guidance that may apply to you.
- Confirm with the collection site whether any fasting is required before your draw.
- Ask whether a specific time of day is preferred for your appointment.
- Tell the collection site about any medications, supplements, or hormone products you use, since these can be discussed with your clinician.
- Bring a photo ID and your test order or requisition if you have one.
- Wear a short-sleeved or loose-sleeved top so the arm is easy to access.
- Follow any additional instructions your ordering clinician or the lab gives you.
Fasting, timing, sample type, and what to bring
Fasting
Fasting requirements for this test vary, and many people are not asked to fast at all. Follow the instructions you are given and confirm with your lab.
Best time to collect
Testosterone levels naturally fluctuate through the day, so the collection site may suggest a specific morning window for your draw. Ask the lab or your clinician whether a particular time is preferred for your situation.
Sample type
Blood draw. The collector will explain the process before starting.
What to bring
- Your order confirmation email, in case the collection site asks to see it
- Your printed lab order or requisition form — the ordering physician prepares it for you after you order, and you print it (or fax it from your account) before visiting
- A government-issued photo ID (most collection sites verify identity at check-in)
- A written list of the medications and supplements you currently take
- A short-sleeved or loose-sleeved shirt for an easy blood draw
- Water to drink before the draw and a light snack for afterward, if your test requires fasting
You do not need an insurance card or a payment method at the collection site: the lab does not bill insurance, and you pay at order time, so there is no copay or deductible. The lab also provides the physician's requisition, so you do not need a separate doctor's referral.

At the collection site
A trained phlebotomist cleans an area on your arm and inserts a small needle into a vein to collect a blood sample into a tube. The draw takes only a few minutes, and the sample is sent to a laboratory for analysis.
Details worth confirming with the collection lab before your visit:
- Does this test require fasting?
- Is a specific time of day preferred for my collection?
- When should I expect my results?
Why the Total Testosterone Testing may be ordered

What results mean
