testicular blood test explained

Overview

A testicular blood test is a simple blood draw that measures certain proteins, called tumor markers, such as AFP, hCG, and LDH. It is used mainly to help diagnose testicular cancer or to see how well treatment is working.

This blood test is not routine for everyone. It is usually done only when a person has symptoms or is at higher risk for testicular cancer.

It is most often performed on men and people assigned male at birth, especially those between ages 15 and 35, or anyone with a testicular lump or other concerning symptoms.

Symptoms

Common symptoms

• A painless lump or swelling in one testicle
• A feeling of heaviness in the scrotum
• A dull ache or pain in the lower belly or groin
• Any change in the size or shape of a testicle

Symptoms in children

• Lumps or swelling in a testicle (though rare, it can happen)
• Unexplained pain in the scrotum or lower abdomen

Symptoms in older adults

• Similar symptoms as younger adults – a lump, swelling, or discomfort in the testicle
• Sometimes back pain or breathing problems if cancer has spread

Causes

Main causes

• The blood test measures tumor markers that can be high due to testicular cancer (especially non-seminoma type)
• Other cancers (like liver or lung) may also raise some markers
• Non-cancer conditions such as liver disease, inflammation, or certain infections can cause elevated levels

Risk factors

• Having an undescended testicle (not in the scrotum at birth)
• Having had testicular cancer in the past
• Having a close family member (father, brother) with testicular cancer
• Being of white ethnicity
• Being between ages 15 and 35

When to see a doctor

See a doctor urgently if:

• If you suddenly feel severe pain in your testicle or scrotum, go to the emergency room immediately.
• If you notice a lump or swelling that appears suddenly and is very tender.

Book a routine appointment if:

• Make an appointment with your GP within a few days if you find a new lump or any change in your testicle.
• If you have a dull ache or feeling of heaviness that lasts more than two weeks.

Diagnosis

The testicular blood test is done by taking a small sample of blood from a vein in your arm. It is very quick and usually painless.

Tests that may be done

• Blood test for tumor markers (AFP, hCG, LDH)
• Ultrasound scan of the scrotum to see the testicle
• CT scan of the chest, belly, and pelvis if cancer is suspected
• Sometimes a biopsy (taking a tiny piece of tissue) or surgery to remove the testicle

What to expect at your appointment

The blood test takes just a few minutes. You may feel a quick pinch. Results usually come back in a few days. Your doctor will explain what the numbers mean and what the next steps are, if any.

Treatment

If the blood test and other tests show testicular cancer, treatment depends on the type and stage. Early-stage cancer is very curable.

Self-care at home

• After a blood test, you can go back to normal activities right away.
• If you have a diagnosis, follow your doctor's advice about rest and activity.
• Keep track of your symptoms and report any changes promptly.

Medical treatments

Treatment may include surgery to remove the affected testicle (orchidectomy), chemotherapy, or radiation therapy. The specific plan is based on the cancer type and how far it has spread. Your healthcare team will explain your options.

When is surgery considered?

Surgery to remove the testicle is often the first step when cancer is found in one testicle. Most people recover well and go on to lead normal lives.

Living with this condition

After treatment, you will have regular follow-up appointments, including blood tests and scans, to make sure everything is okay. Many people return to work, school, and hobbies within a few weeks.

Lifestyle tips

• Stay active with gentle exercise as you feel able.
• Avoid heavy lifting or strenuous activity right after surgery, but ask your doctor when you can resume.
• Practice self-examination of your remaining testicle every month.

Diet and exercise

Eat a balanced diet with plenty of fruits, vegetables, and whole grains. Moderate exercise, like walking, can help with recovery and mood. Always check with your doctor before starting a new activity.

Mental health and emotional wellbeing

A cancer diagnosis can be stressful and frightening. It is normal to feel anxious, sad, or worried. Talking to a counselor, joining a support group, or reaching out to loved ones can help.

Prevention

Most cases of testicular cancer cannot be prevented, but finding it early gives the best chance of a cure. Monthly self-examination can help you notice changes early.

Screening programmes

There is no routine screening test for testicular cancer in the general population. However, if you have risk factors, your doctor may recommend regular exams and possibly blood tests.

Complications

If left untreated

• Testicular cancer can spread to other parts of the body, such as the lungs, liver, or brain.
• Advanced cancer can cause pain, breathing difficulties, and other serious health problems.

Long-term outlook

Testicular cancer has one of the highest cure rates, especially when found early. With modern treatment, more than 95% of people survive long-term. Even if the cancer has spread, it is often treatable. Your medical team will work with you to give you the best possible outcome.
