Testosterone Test key facts

Updated on 4 Oct 2024

What is a Testosterone test kit and how does it work?

A testosterone home test kit is used to measure testosterone levels at home without the need for a doctor’s visit. The kit typically contains everything needed to collect a sample and to post it to a lab for testing. Results are normally available within 2 to 3 days.

Symptoms of low testosterone: When to consider testing

Testosterone affects sex drive (libido), muscle mass, strength, healthy bones, energy levels, fertility, and mood. Your testosterone levels can be affected by alcohol consumption, stress, and even exercise. Low testosterone levels can cause low sex drive and low mood. Testosterone levels also naturally decrease in both men and women with age.

You can use our easy and convenient home testosterone finger-prick blood test kit to measure your testosterone levels if you have any of the above symptoms and are concerned you may have low testosterone levels.

What does a testosterone test kit measure?

The testosterone function test kit checks for testosterone as the specific biomarkers in your blood. Testosterone is a sex hormone that helps to regulate sex drive, control bone and muscle mass, strength, fat distribution, and the production of sperm and red blood cells in men. Testosterone is produced in the testicles in men and, in the ovaries and adrenal glands in women in smaller amounts. Testosterone levels fall naturally in men after the age of 30, causing low libido, erectile dysfunction, fatigue and difficulty in maintaining muscle mass.

Testosterone testing for men and women: What’s the difference?

  • Normal testosterone levels for men are 300–1,000 ng/dL (nanograms per deciliter). Normal levels for women are 15–70 ng/dL
  • After puberty, men produce 20 times more testosterone than women. Also, in women, around 80% of testosterone is attached to SHBG (sex hormone binding globulin), so the free androgen index is a more accurate measure of testosterone levels than free testosterone
  • In women, testosterone testing can identify conditions like polycystic ovary syndrome, the cause of irregular periods, and difficulties in getting pregnant

How to use an at-home Testosterone test kit

What are the benefits of the Testosterone blood test?

  • All test kits are security sealed with confidential health test results
  • All laboratory testing is performed in an ISO:15189 accredited clinical laboratory

FAQ’s

What can affect testosterone levels?

Stress, alcohol consumption and exercise can all affect the amount of testosterone your body makes.

Can I use this test if I am undergoing testosterone replacement therapy (TRT)?

Yes. The Testosterone Blood Test can be used to monitor your hormone levels whilst taking TRT.

Does the testosterone test measure total testosterone or free testosterone?

Testosterone in your blood can be attached to proteins or not attached to proteins (free testosterone). Free testosterone is available for your body’s cells to use, while attached testosterone is not. The testosterone test measures the total testosterone level which is a combination of the attached and free testosterone.

When is the best time to take the Testosterone Blood Test?

You are recommended to take the test in the morning when your testosterone levels are at their peak.

Can women use testosterone test kits?

This test is suitable for men and women, as testosterone is also an essential hormone for women. Women may experience low levels of testosterone during the menopause. This can lead to poor bone health, vaginal dryness, and reduced sex drive.

Women may also experience high testosterone levels due to health conditions such as Polycystic Ovary Syndrome (PCOS). Women can take the PCOS test, to find out if their hormone levels are causing their symptoms of PCOS.

What causes low testosterone levels in men?

Factors which may cause low testosterone include:

  • Damage to the testes
  • High-stress levels
  • An unhealthy BMI
  • Steroid abuse
  • Type 2 diabetes
  • Cancer treatment
  • Tumours affecting hormone production, such as that of the pituitary gland
  • Smoking
  • Excessive alcohol intake
  • Lack of exercise
  • Lack of sleep

Do testosterone levels fluctuate?

Yes, testosterone levels change throughout the day and from week to week. Stress, exercise, and alcohol intake can all affect your testosterone levels.

Is there a male menopause?

The natural decline in testosterone levels in men is sometimes called male menopause, manopause, or andropause. The age-related fall in testosterone in men is usually very gradual, and most men will not experience any symptoms of low testosterone.

Can I increase my testosterone levels naturally?

Yes. With some diet and lifestyle changes such as, getting good quality sleep, eating a healthy, balanced diet, exercising regularly, losing weight if you’re overweight, managing your alcohol intake, stopping smoking and managing your stress levels.

What are normal testosterone levels?

Normal testosterone levels for men are 300–1,000 ng/dL (nanograms per deciliter). Normal levels for women are 15–70 ng/dL.

How accurate are at-home testosterone tests?

At-home testosterone tests are not as accurate as in-person tests. The accuracy of at-home testosterone tests depends on the test type, human error, sample collection and the time of day it was collected, and other medications being taken.

What are the symptoms of low testosterone?

Low testosterone levels can cause low sex drive, low bone and muscle mass, reduced strength, increased fat distribution, and a reduction in the production of sperm and red blood cells in men.

How often should I test my testosterone levels?

How often you test your testosterone levels depends on a number of factors, such as your symptoms, age, treatment and test results.

What should I do if my testosterone levels are low?

If you have low testosterone levels, try:

  • Reducing your stress levels
  • Lose weight if you are overweight or obese
  • Stop smoking
  • Reduce your alcohol intake
  • Exercise
  • Improve the quality of your sleep
  • Consider testosterone replacement therapy

How can I check my testosterone level at home?

Is the service available in the United States and the United Kingdom?

Do I need to pay for this service?

Yes, this is currently a private service. However, in the UK, this may change and may be funded by the NHS, in the future. In the US, it may be possible it is covered by insurance but this depends on your health plan.

What happens when I order a Home Health Testing kit?

We will send you the test kit you have ordered, which will have instructions on how to collect your sample. Once collected, you simply pop it into the pre-paid envelope and send it to our laboratory.

How will I know how to use the test kit?

Instructions for sample collection are enclosed in each collection kit and can be found in the video below.

How do I return the sample to your laboratory?

We supply you with a return system package. Use this to send back the sample. Samples are fully tracked and can be posted from any Royal Mail post box, for UK customers, or USPS, for US customers.

How long does it take to get the test results back and what happens next?

Test results can take up to 10 working days to process from the day we receive your sample back. When we have processed your results, you will be sent a notification which will appear in your ‘My Notifications’ section on your dashboard, which will advise you that your results are now in the ‘My Documents’ section of your dashboard, however, the test results will be locked and will not be viewable. The notification will include a link that will allow you to book a consultation with one of our Home Health Testing counsellors.

How do I book a consultation?

Once you click ‘Book Consultation’, you will be taken to a consultation booking screen. You will then need to select a date and time that is convenient for you, along with the preferred language of the prescribing clinician you wish to choose. You will then see a list of all available clinicians. From this list, you can filter clinicians by gender and then select the clinician you would like to confirm for your booking. Once you have approved this, you will see a summary of the appointment including preliminary information about the consultation. At this point, you will also be able to add a reminder to your calendar. Always ensure your account health profile is up to date before any consultation. This ensures that our clinicians have the most up-to-date information about your current health status and anything that may influence their prescribing decisions. You will receive a push notification and email reminding you of your consultation, 30 minutes before it is due to start.

What happens during the consultation?

At the consultation, the clinician will discuss what the results mean for you and the medication you are currently taking. If the clinician decides that your doctor may need to review your medication or dose, they will send a referral letter, including the test results, to your doctor. If the clinician decides the results do not affect the way you process your medications then the consultation will end.

What happens at the end of the consultation?

At the end of the consultation, you will receive a notification which will summarise the outcomes of the consultation. It will also advise if a doctor referral was made, by way of letter. If a GP referral letter was issued, you will be able to view a copy of this in the ‘My Documents’ section of your dashboard. At this stage, your test results will also be unlocked and you will be able to download it and share it with any other healthcare provider.

Are my results confidential?

Yes, we follow strict General Data Protection Regulations (GDPR) which came into force in May 2018. This places legal requirements on ourselves to ensure your personal data is managed securely with utmost confidentiality. Records are maintained of the processing that is carried out and reported when breaches of the regulation do occur. Our platform is also HIPAA compliant which means we are able to handle PHI (Personal Health Information) securely.

Are you able to prescribe a treatment plan, if my results indicate I need treatment?

For UK users, our prescribing clinicians may be able to provide a private treatment plan, subject to their clinical judgment. Unfortunately, we do not operate a service where you can request a certain medication.

What are the limitations of the Home Health Testing service?

All test kits have a certain level of inaccuracy, therefore results can only be taken as estimates. It should be noted all tests are performed in strict accordance with the manufacturer’s instructions and test performance is regularly monitored through internal and external quality control for test result interpretation.

We do not recommend sending samples back between Friday noon and Monday morning due to delays.

Are there any concerns or risks I need to be aware of?

Tests cannot be performed if samples fall short of the quality, volume, or other eligibility criteria. In these cases, the laboratory may need to reject the samples, and not carry out processing. Sometimes the laboratory is able to rectify a situation and although turnaround times may be affected, it avoids having to arrange for samples to be taken again.

Tests cannot be performed if incorrect sample types are received; samples are received unprotected from light when they are required to be covered at the point of venepuncture; samples are received in incorrect containers; no sample received; samples mislabelled, unlabelled, or with no forms, or no clinical information, samples are broken or have leaked in transit; samples are contaminated (e.g. being in the same bag as a leaking sample); sample stability time has been exceeded (stability time is test dependant, and also refers to tests that can only be carried out on certain days of the week); samples are received in expired tubes.

The laboratory will not accept samples packaged with needles of any kind.
