The tool

How it works, what it tells you, what it doesn't.

This screening quiz uses the ADAM questionnaire, a 10-question tool developed at Saint Louis University to flag symptoms linked to low testosterone. You answer yes or no to questions about libido, energy, mood, strength, and more, and it tells you whether your answers meet the ADAM criteria for possible androgen deficiency. It is deliberately sensitive, so it catches most men with low testosterone but also flags some men whose levels are normal. That is the point of a screener: a positive result is a reason to get blood work, not a diagnosis. Only a morning blood draw can confirm low testosterone.

What Is the ADAM Questionnaire?

The ADAM (Androgen Deficiency in the Aging Male) questionnaire is a validated clinical screening tool developed by researchers at Saint Louis University. It’s used by healthcare providers as a quick initial assessment for symptoms of low testosterone.

The questionnaire has an 88% sensitivity rate, meaning it correctly identifies most men with low testosterone. However, its specificity is around 60%, which means some men will screen positive even with normal testosterone levels. That’s why this is a screening tool, not a diagnosis. A positive result means “get your blood tested,” not “you definitely have low T.”

Normal Testosterone Levels by Age

Age Range	Low (ng/dL)	Normal Range (ng/dL)	Optimal Range (ng/dL)
20-29	Below 264	264 – 916	500 – 916
30-39	Below 252	252 – 916	450 – 916
40-49	Below 237	237 – 870	400 – 870
50-59	Below 215	215 – 794	350 – 794
60+	Below 196	196 – 740	300 – 740

These ranges are based on morning, fasting blood draws. Testosterone levels fluctuate throughout the day and are highest in the morning. A level drawn at 3pm after a meal will be significantly lower than one drawn at 8am fasted. This is why most guidelines require two separate morning draws before diagnosing hypogonadism.

“Normal” range doesn’t mean “optimal.” A 35-year-old with a total testosterone of 280 ng/dL is technically in range but at the very bottom. Many men with symptoms experience significant improvement when levels are optimized to the upper portion of the normal range.

What Blood Work Should You Get?

If your ADAM screening is positive or you have ongoing symptoms, ask your doctor for these tests:

Test	Why It Matters
Total Testosterone	Your primary number. Needs to be drawn in the morning, fasting.
Free Testosterone	The portion your body can actually use. Some men have normal total T but low free T.
SHBG	Binds to testosterone, making it unavailable. High SHBG can cause low free T even with normal total T.
LH	Tells you whether the problem is in your brain (secondary) or testes (primary). High LH + low T = primary. Low LH + low T = secondary.
FSH	Works alongside LH. Important for fertility assessment.
Estradiol (E2)	Elevated estrogen can suppress testosterone and cause overlapping symptoms.
CBC	Baseline before starting any treatment. Includes hematocrit, which TRT can elevate.
Comprehensive Metabolic Panel	Liver and kidney function baseline.
Thyroid Panel (TSH, Free T4)	Thyroid dysfunction mimics many low T symptoms. Rule it out.
Prolactin	Elevated prolactin can suppress testosterone. Usually only checked if levels are very low.

If Your Doctor Prescribes TRT

Starting testosterone replacement therapy can feel overwhelming. The most important things to know:

It takes 4-8 weeks to feel the initial effects and 3-6 months for full body composition changes
You’ll need regular blood work (every 3-6 months) to monitor your levels and safety markers
Injection frequency matters - many men do better on more frequent, smaller doses (daily or every-other-day) rather than large weekly injections

Questions

Frequently Asked Questions

How accurate is the ADAM questionnaire?

The ADAM questionnaire has 88% sensitivity (catches most cases of low T) but only 60% specificity (some false positives). It's designed to cast a wide net. A positive screening means you should get blood work done, not that you definitely have low testosterone. Think of it as a reason to investigate, not a diagnosis.

What testosterone level is considered "low"?

Most guidelines define hypogonadism as total testosterone below 300 ng/dL on two separate morning, fasting blood draws. However, symptoms don't follow a hard cutoff. Some men feel fine at 350 and others have significant symptoms at 400. Free testosterone may be more important than total testosterone for predicting symptoms.

Can lifestyle changes raise testosterone?

Yes, modestly. Quality sleep (7-9 hours), resistance training, maintaining a healthy body weight, managing stress, and adequate vitamin D and zinc intake all support natural testosterone production. However, lifestyle changes typically raise levels by 50-150 ng/dL. If your starting point is 200, lifestyle alone may not be sufficient.

At what age should I get my testosterone checked?

There's no universal recommendation, but if you have symptoms (fatigue, low libido, depression, difficulty building muscle, brain fog), it's worth checking regardless of age. Many men in their 30s discover they have low testosterone. The average testosterone level in men has been declining by about 1% per year across all age groups, so "young" doesn't mean "safe."

I scored positive. Should I be worried?

A positive screening is a reason to be informed, not alarmed. It means your symptoms are consistent with what men with low testosterone experience. The next step is straightforward: talk to your doctor and get a blood test. Many causes of these symptoms are treatable, whether the answer turns out to be low testosterone, thyroid issues, vitamin deficiency, or something else.

Can I take this quiz for someone else?

This quiz is designed for self-assessment. The questions ask about subjective experiences (libido, energy, mood) that only the individual can accurately report. If you're concerned about someone else, encourage them to take it themselves and discuss the results with their doctor.

Does insurance cover testosterone testing?

Most insurance plans cover testosterone blood tests when ordered by a doctor with appropriate symptoms documented. If your doctor notes fatigue, low libido, or other relevant symptoms along with the ADAM screening results, insurance typically covers the lab work. Direct-to-consumer lab services are also available for $50-100 if you want to check without a doctor visit first.
