Wikipedia suggests 'mE/l' is the dutch or german translation (using 'eenheid'/'einheit' for 'unit') for 'mU/l', which can also be written as 'mIU/l'.

The article mentionsThe IU should not be confused with the enzyme unit, also known as the International unit of enzyme activity and abbreviated as U.. Is it safe to assume that in case of the unit 'mU/l' one never means the enzyme unit? I figure this is because the enzyme unit specifies a rate of conversion, which is not a blood value and would be meaningless to specify 'per liter'.

I have also encountered 'mEq/l', of which I am pretty sure it is different from 'mU/l', going by the wikipedia article.

What Is an Alanine Aminotransferease (ALT) Test?

The alanine aminotransferase (ALT) test is a blood test that checks for liver damage. Your doctor can use this test to find out if a disease, drug, or injury has damaged your liver.

Your liver does a lot of important things for you:

  • It makes a fluid called bile that helps your body digest food.
  • It removes waste products and other toxins from your blood.
  • It produces proteins and cholesterol.

Diseases such as hepatitis and cirrhosis can damage your liver and prevent it from doing its many jobs.

Thank you for your interesting posts. Don’t you think the term “normal value” is better to change with “Reference Interval” as explained in CLSI and ISO terminology?

This is very impressive and shows passion for the profession on your side. What a commendable effort to make such a compilation for sharing. However may I know if a global geographical distribution difference was calculated as it has proved in my over 35 years of service in the field that blood value (normal) range from caucasian communities are not the same with the Afro-comminities. All the same your effort,once again,is very commendable.

Complete Blood Count (CBC)

The CBC test examines cellular elements in the blood, including red blood cells, various white blood cells, and platelets.

Here is a list of the components that are normally measured, along with typical values.

WBC (white blood cell) leukocyte count

White blood cells help fight infections, so a high white blood cell count could be helpful for identifying infections. It may also indicate leukemia, which can cause an increase in the number of white blood cells. On the other hand, too few white blood cells could be caused by certain medications or health disorders.

Normal range: 4,300 to 10,800 cmm

WBC (white blood cell) differential count

This test measures the numbers, shapes, and sizes of various types of white blood cells listed above. The WBC differential count also shows if the numbers of different cells are in proper proportion to each other. Irregularities in this test could signal an infection, inflammation, autoimmune disorders, anemia, or other health concerns.

RBC (red blood cell) erythrocyte count

We have millions of red blood cells in our bodies, and this test measures the number of RBCs in a specific amount of blood. It helps us determine the total number of RBCs and gives us an idea of their lifespan, but it does not indicate where problems originate. So if there are irregularities, other tests will be required.

Normal range: 4.2 to 5.9 million cmm

Hematocrit (Hct)

Useful for diagnosing anemia, this test determines how much of the total blood volume in the body consists of red blood cells.

Normal range: 45% to 52% for men 37% to 48% for women

Hemoglobin (Hgb)

Red blood cells contain hemoglobin, which makes blood bright red. More importantly, hemoglobin delivers oxygen from the lungs to the entire body then it returns to the lungs with carbon dioxide, which we exhale. Healthy hemoglobin levels vary by gender. Low levels of hemoglobin may indicate anemia.

Normal range: 13 to 18 g/dL for men 12 to 16 g/dL for women

Mean corpuscular volume (MCV)

This test measures the average volume of red blood cells, or the average amount of space each red blood cell fills. Irregularities could indicate anemia and/or chronic fatigue syndrome.

Normal range: 80 to 100 femtoliters

Mean corpuscular hemoglobin (MCH)

This test measures the average amount of hemoglobin in the typical red blood cell. Results that are too high could signal anemia, while those too low may indicate a nutritional deficiency.

Normal range: 27 to 32 picograms

Mean corpuscular hemoglobin concentration (MCHC)

The MCHC test reports the average concentration of hemoglobin in a specific amount of red blood cells. Here again, we are looking for indications of anemia if the count is low, or possible nutritional deficiencies if it’s high.

Red cell distribution width (RDW or RCDW)

With this test, we get an idea of the shape and size of red blood cells. In this case, “width” refers to a measurement of distribution, not the size of the cells. Liver disease, anemia, nutritional deficiencies, and a number of health conditions could cause high or low RDW results.

Platelet count

Platelets are small portions of cells involved in blood clotting. Too many or too few platelets can affect clotting in different ways. The number of platelets may also indicate a health condition.

Normal range: 150,000 to 400,000 mL

Mean Platelet Volume (MPV)

This test measures and calculates the average size of platelets. Higher MPVs mean the platelets are larger, which could put an individual at risk for a heart attack or stroke. Lower MPVs indicate smaller platelets, meaning the person is at risk for a bleeding disorder.

Normal range: 7.5 to 11.5 femtoliters

Please note: If your doctor says you’re fine but your tests results are somewhat different from the range shown here, don’t be alarmed. Some labs interpret test results a bit differently from others, so don’t consider these figures absolutes.

What Are Normal Levels of Insulin?

Many people carefully monitor their glucose levels for signs of diabetes, but how many do the same with insulin levels? Your body requires constant circulation of insulin in the blood all the time, even when you're not eating. The level of insulin circulating in your bloodstream is a good indication of your overall health and may be able to predict your risk of sudden death, so it's really useful to know your insulin levels. But what levels of insulin are normal, and how do you know when things have gone awry?

What Are Normal Insulin Levels?

Your insulin levels will be typically measured in micro units per milliliter (mcU/ml or mIU/ml). However, experts often disagree on what should be the "ideal" levels of glucose.

According to Health Central, the levels should be about 10-20 mcU/ml, while a Dr. Mercola says the normal levels should be under 5 mcU/ml. However, according to Stephen Guyenet, a researcher from University of Washington, the average blood insulin levels in the American population are 8.4 mIU/ml for women and 8.6 mIU/ml for men, but given the prevalence of obesity and metabolic disorders in the US, the ideal level is probably between 2-6 mcU/ml.

Insulin levels are often assessed after fast for some time. One study, carried out in Arizona, found that women who had a fasting insulin level of 8 mcU/ml were more than twice as likely to develop prediabetes as those with 5 mcU/ml insulin levels. Women with 25 mcU/ml fasting insulin level had over 5 times the risk of prediabetes than women with 5 mcU/ml insulin level.

Of course, the amount of insulin in the bloodstream will fluctuate in accordance with the levels of glucose. For more information on this, read the table below (information source: Medscape):

19 Often Used Abbreviations in Blood Tests

Blood tests are used to determine many medical conditions. They are often used to check if drugs are present in a person's system, if medications for an illness are effective, if there are any mineral imbalance within the body and if the organs are functioning properly. It is highly possible that you will require a blood test at one point in your life. There are numerous blood test abbreviations, knowledge of these abbreviations will help you ascertain what blood tests results mean, and help you gather a clear understanding of blood tests in general.

11 Common Blood Test Abbreviations

There are 11 common blood test abbreviations, understanding what they mean will help you further understand your blood test results.

Blood Test Abbreviation


This refers to the measurement of good cholesterol (HDL or high-density lipoprotein) and bad cholesterol (LDL or low-density lipoprotein) within your blood. HDL helps to limit LDL, meaning high levels of HDL is a good thing and can help to prevent things such as heart disease.

Elevated CPR, or C-Reactive Protein, levels indicate inflammation within the body. Short spikes can be expected in some instances, for example,when the immune system battles infection. Consistenthigh levels of CPR can indicate underlying health problems.

CBC, or complete blood count, is a test comprising of 15 different readings that helps to give your health care provider an account of your overall health. The tests measure numerous things within your blood, like red and white blood cell levels.

TSH, or thyroid stimulating hormone, helps to regulate the function of your thyroid, which keeps your metabolism functioning properly. Low levels of TSH can lead to weight loss and anxiety high levels can lead to weight gain, depression and fatigue. Normal level is said to be between 0.35 and 3uIU/ml.

Although this is not always included in standard blood tests, testing for levels of vitamin D in the blood is also very important. High levels can be toxic, and low levels can cause you to feel fatigued and achy.

Health care professionals use FBC, or full blood count, to get an overall picture of your health. Usually,these tests don&rsquot pinpoint specific illnesses, but they can help to point your doctor in the right diagnosis direction.

An ESR, or erythrocyte sedimentation rate, test measures the time it takes for red blood cells to descend to the bottom of a test tube. The more rapid they fall, the more likely it is that high levels of inflammation have occurred.

INR, or international normalized ratio, test is used to determine whether you blood is clotting normally. It also assesses the effectiveness of Warfarin therapy which slows down the clotting of the blood and is used to aid in preventing thrombosis.

The LFT, or liver function test, measures numerous proteins, enzymes and waste products processed or made by the liver. This can help to identify many liver complications, as well as gall stones. It is important to remember that some medications can affect the results of an LFT, making it inaccurate.

Urate is a breakdown product of RNA and DNA, which is usually excreted out of the body through urine. If there are high levels of urate in the blood, it can crystalize and lead to gout or inflammation in the joints. This test checks for levels of urate to determine whether there are any abnormalities.

A CMP, or comprehensive metabolic panel, provides your health care provider with a distinct picture of your body's metabolism and chemical balance. A CMP will check your levels of numerous substances, including bilirubin, albumin, calcium, sodium, potassium, chloride, etc.

8 Other Blood Test Abbreviations for You

Blood tests reports contain a vast amount of abbreviations that can be confusing. In the hope of further clarifying what they mean, below are 8 other blood test abbreviations that you should know:


The levels of white blood cells in your blood.

Know the Measurement Abbreviations in Blood Tests

Knowing what common blood test abbreviations mean will be useless if you don&rsquot understand what the measurements mean. Below is a table detailing some of the common measurements.

Safe Adequate Intake

Signs & Symptoms of Vitamin B-12 & Vitamin D Deficiencies

Your blood vitamin D level is affected by your sun exposure and dietary intake. A vitamin D level of about 50 nmol/L corresponds to the RDA of 600 IU per day, which is considered adequate for bone and overall health in most people. A study published in the February 2001 issue of "The American Journal of Clinical Nutrition" assessed the efficacy and safety of 1,000 and 4,000 IU per day in middle-aged men and women over a 5-month period. Serum vitamin D levels plateaued at 69 and 96 nmol/L in the low and high intake groups, respectively, without changing serum calcium levels. These data support the adequacy and safety of the Institute of Medicine’s vitamin D intake recommendations.

  • Your blood vitamin D level is affected by your sun exposure and dietary intake.
  • Serum vitamin D levels plateaued at 69 and 96 nmol/L in the low and high intake groups, respectively, without changing serum calcium levels.
