Angiotensin Converting Enzyme (ACE) Test

Sarcoidosis, Gaucher’s Disease, Leprosy

The ACE Level Test is used to measure the amount of Angiotensin-Converting Enzyme (ACE) present in the body.

The right amount of ACE in the body is responsible for maintaining and regulating the body’s blood pressure in a normal state. ACE is an entity that converts one type of hormone to another type, i.e., from the Angiotensin, I hormone to an active vasoconstrictor called the Angiotensin II.

Angiotensin II causes the arteries to contract temporarily and as a result, it raises the pressure of the blood flowing inside those arteries. When the body has either too low or too high ACE levels in the blood, it usually suggests some ACE-related health disorder.

Some of the most common health issues related to inappropriate ACE levels include Sarcoidosis, Leprosy, Tuberculosis, Hyperthyroidism, Starvation and other lung disorders like Lung Cancer.

So, undergoing the ACE Level Test means that your healthcare practitioner has observed one or more symptoms of an ACE-level health disorder and wants to check the ACE level for further treatment (if there is any required in the first place).

In India, the occurrence of Sarcoidosis and other ACE level-related issues like Hypertension has been a concerning factor for the Indian medical authorities. Their diagnosis still remains to be a problematic area.

Other Names of the ACE Level Test

What Does the ACE Level Test Detect and Who is This Prescribed For?

Going for the ACE Level Test helps diagnose the following conditions: 

• Sarcoidosis

Sarcoidosis is a lung disease that is linked to a high amount of ACE in the body. So, conducting an ACE Level Test is used for the diagnosis of this lung condition.

• Gaucher’s Disease

Gaucher’s Disease is a condition where fatty substances build up in the body and prevent other organs like the spleen and liver from carrying out their functions to keep the body healthy. This disease is also linked to the occurrence of high ACE levels. Therefore, conducting the ACE Level test can serve as a primary diagnostic test.

• Leprosy

Leprosy is a health disorder that can lead to skin lesions and severe nerve damage. This health condition is linked to the high levels of Angiotensin-Converting Enzyme in the bloodstream. So, the ACE Level Test can help in the diagnosis of this health condition.

Apart from the diagnosis, ACE Level Test can also be used in monitoring the results of various treatments like the sarcoidosis treatment, where the ACE level should be going down as the treatment progresses.

Doctors prescribe ACE Level Test for people who show the following symptoms:

• Coughing, wheezing or experiencing shortness of breath
• Fever
• Experiencing extreme tiredness
• Sharp chest pain
• Vision problems
• Unexplained weight loss and a loss of appetite
• Soreness or stiffness in joints
• Dryness in mouth
• Headache
• Unusual changes in the skin, sores, rashes and hardened spots

The following table is a guide to understanding the various ACE Level test results:

Different laboratories often have different ways of reporting the ACE level in the body. For adults, the range is mentioned above.

If you go for the ACE Level Test for kids, please note that the normal range of ACE levels in the body is generally higher than in adults. This happens because as we grow older, the level of Angiotensin-Converting Enzymes in the body starts declining.

So, make sure to check with your lab technician to know about the normal test ranges for children in their lab. You should also make a point to consult the child’s doctor right after you talk to the lab technician.

Higher than normal ACE levels may suggest Sarcoidosis. A chronic disease that causes enlargement of lymph nodes in various parts of the body. If you are on treatment and have gotten back to normal levels of ACE, then it is still not a confirmation of not having any disease like Sarcoidosis. Do not stop or alter the doses of medication.

If you have symptoms but got a normal ACE Level Test result, your doctor will most probably ask you to go for further tests to get to the root of the underlying health problem.

If you have high levels of ACE Levels and also have symptoms, then your doctor might diagnose you with one of the problems related to ACE.

Some of the health issues related to high levels of ACE include:

• Sarcoidosis
• Tuberculosis
• Primary biliary cirrhosis
• Alcoholic liver disease
• Lung disease
• Hyperthyroidism
• Diabetes
• Leprosy
• Hyperparathyroidism
• Multiple myeloma
• Amyloidosis
• Gaucher’s Disease

However, you should keep in mind that getting a higher range of ACE levels on your ACE Level Test report does not automatically mean that you have a health disorder. Further tests are necessary to confirm the disorder.

The ACE Level Test is conducted with the help of a blood sample, which is drawn from the arm.

Test Preparation for ACE Level Test?

You will be asked by your lab technician and healthcare professional not to eat anything and fast for at least 12 hours before the ACE Level Test blood sample is taken. To make fasting easier for yourself, you can opt to fast overnight and then go for the ACE Level Test in the morning.

If you are on medicines and regularly take blood thinners, then speak with your doctor before taking the ACE Level Test. Your doctor may even ask you to stop taking a certain dose right before the test (or a day before) to avoid any interference with the actual test results.

The ACE Level test blood sample will be drawn from a vein in your arm and does not involve any major risks as a part of the procedure. However, in some cases, the person ends up experiencing fatigue and dizziness. Carry a light snack and also ask someone to drive you back home.

Test Inclusions: What ACE Level Test Parameters are Included

The ACE Level Test results can often be influenced by the way the particular laboratory conducts the tests on the collected blood sample. For example, some laboratories may report the results in the nmol/mL/min unit, whereas some other laboratories may choose the microliters unit.

The age of the person can also influence the ACE Level Test results. This is because, for kids, the ACE levels in the body are generally higher than the ACE levels found in adults. So, if you are getting your kid tested for their ACE level, their reference ranges for normal ACE Level test results will be different and need to be consulted with the doctor.

How Frequently Should You Take the ACE Level Test?

The ACE Level Test is prescribed by your healthcare practitioner only on observing certain symptoms in you that may be pointing to an imbalance in ACE Level. This imbalance can trigger health issues which then show up in the form of certain specific symptoms.
