Basics: Testing: Prolactin

prolactin (PRL) test measures how much of a hormone called prolactin you have in your blood. The hormone is made in your pituitary gland, which is located just below your brain.

When women are pregnant or have just given birth, their prolactin levels increase so they can make breast milk. But it’s possible to have high prolactin levels if you’re not pregnant, and even if you’re a man.

Your doctor may order a prolactin test when you report having the following symptoms:

For women

For men

  • Decreased sex drive
  • Difficulty in getting an erection
  • Breast tenderness or enlargement
  • Breast milk production (very rare)

For both

Causes of Abnormal Prolactin Levels

Normally, men and nonpregnant women have just small traces of prolactin in their blood. When you have high levels, this could be caused by:

Also, kidney diseaseliver failure, and polycystic ovarian syndrome (a hormone imbalance that affects ovaries) all can affect the body’s ability to remove prolactin.

How the Test Is Done

You don’t need to make any special preparations for a prolactin test. You will get a blood sample taken at a lab or a hospital. A lab worker will insert a needle into a vein in your arm to take out a small amount of blood.

Some people feel just a little sting. Others might feel moderate pain and see slight bruising afterwards.

After a few days, you’ll get the results of your prolactin test in the form of a number.

The normal range for prolactin in your blood are:

  • Males: 2 to 18 nanograms per milliliter (ng/mL)
  • Nonpregnant females: 2 to 29 ng/mL
  • Pregnant females: 10 to 209 ng/mL

If Your Prolactin Levels Are High

If your value falls outside the normal range, this doesn’t automatically mean you have a problem. Sometimes the levels can be higher if you’ve eaten or were under a lot of stress when you got your blood test.

Also, what’s considered a normal range may be different depending on which lab your doctor uses.

If your levels are very high — up to 1,000 times the upper limit of what’s considered normal — this could be a sign that you have prolactinoma. This tumor is not cancer, and it is usually treated with medicine. In this case, your doctor may want you to get an MRI.You’ll lie inside a magnetic tube as the MRI device uses radio waves to put together a detailed image of your brain. It will show whether there’s a mass near your pituitary gland and, if so, how big it is.

If Your Levels Are Low

If your prolactin levels are below the normal range, this could mean your pituitary gland isn’t working at full steam. That’s known as hypopituitarism. Lower levels of prolactin usually do not need medical treatment.

Certain drugs can cause low levels of prolactin. They include:

Treatment

Not all cases of high prolactin levels need to be treated.

Your treatment will depend on the diagnosis. If it turns out to be a small prolactinoma or a cause can’t be found, your doctor may recommend no treatment at all.

In some cases, your doctor may prescribe medicine to lower prolactin levels. If you have a prolactinoma, the goal is to use medicine to reduce the size of the tumor and lower the amount of prolactin.

ℹ️ Basics: Testing: What Is a TSH Test?

A TSH test is done to find out if your thyroid gland is working the way it should. It can tell you if it’s overactive (hyperthyroidism) or underactive (hypothyroidism). The test can also detect a thyroid disorder before you have any symptoms. If untreated, a thyroid disorder can cause health problems.

TSH stands for “thyroid stimulating hormone” and the test measures how much of this hormone is in your blood. TSH is produced by the pituitary gland in your brain. This gland tells your thyroid to make and release the thyroid hormones into your blood.

The Test

The TSH test involves simply drawing some blood from your body. The blood will then be analyzed in a lab. This test can be performed at any time during the day. No preparation is needed (such as overnight fasting). You shouldn’t feel any pain beyond a small prick from the needle in your arm. You may have some slight bruising.

In general, there is no need to stop taking your medicine(s) before having your TSH level checked. However, it is important to let the doctor know what medications you are taking as some drugs can affect thyroid function. For example, thyroid function must be monitored if you are taking lithium. While taking lithium, there is a high chance that your thyroid might stop functioning correctly. It’s recommended that you have a TSH level test before starting this medicine. If your levels are normal, then you can have your levels checked every 6 to 12 months, as recommended by your doctor. If your thyroid function becomes abnormal, you should be treated.

High Levels of TSH

TSH levels typically fall between 0.4 and 4.0 milliunits per liter (mU/L), according to the American Thyroid Association. Ranges between laboratories will vary with the upper limit generally being between 4 to 5. If your level is higher than this, chances are you have an underactive thyroid.

In general, T3 and T4 levels increase in pregnancy and TSH levels decrease.

Low Levels of TSH

It’s also possible that the test reading comes back showing lower than normal levels of TSH and an overactive thyroid. This could be caused by:

Graves’ disease (your body’s immune system attacks the thyroid)

Too much iodine in your body

Too much thyroid hormone medication

Too much of a natural supplement that contains the thyroid hormone

If you’re on medications like steroids, dopamine, or opioid painkillers (like morphine), you could get a lower-than-normal reading. Taking biotin (B vitamin supplements) also can falsely give lower TSH levels.

The TSH test usually isn’t the only one used to diagnose thyroid disorders. Other tests, like the free T3, the free T4, the reverse T3, and the anti-TPO antibody, are often used too when determining whether you need thyroid treatment or not.

Treatment

Treatment for an underactive thyroid usually involves taking a synthetic thyroid hormone by pill daily. This medication will get your hormone levels back to normal, and you may begin to feel less tired and lose weight.

To make sure you’re getting the right dosage of medication, your doctor will check your TSH levels after 2 or 3 months. Once they are sure you are on the correct dosage, they will continue to check your TSH level each year to see whether it is normal.

If your thyroid is overactive, there are several options:

Radioactive iodine to slow down your thyroid

Anti-thyroid medications to prevent it from overproducing hormones

Beta blockers to reduce a rapid heart rate caused by high thyroid levels

Surgery to remove the thyroid (this is less common)

Your doctor may also regularly check your TSH levels if you have an overactive thyroid.

⁉️ Cushing’s Myths and Facts: Cushing’s is RARE, No one has Cushing’s!

Myth: “Cushing’s is RARE”, “No one has Cushing’s!”, “It is literally impossible for you to have Cushing’s Disease!”

myth-busted

Fact: We have all been guilty of referring to Cushing’s as a “Rare” disease. I*, myself, say this all the time. In fact, the statistics state that only about 2 in every million people are afflicted with this disease. However, these are documented cases.

In reality, Cushing’s is not as rare as we once thought. The fact is that Cushing’s is just rarely diagnosed! Non-experts tend to not test accurately and adequately for Cushing’s.

With an inappropriate protocol for testing, the prevalence of accurate diagnoses decreases. Cushing’s experts DO understand how extensive and difficult the diagnostic process is, so they tend to be more deliberate and thorough when exploring possible Cushing’s in their patients. Cushing’s patients who cycle also have to be more persistent in asking for adequate testing so that they are appropriately diagnosed.

The following video is an accurate portrayal of what many patients experience when trying to get help for their symptoms:
