TLC stands for Total Leukocytes Count and an increase in TLC in our blood usually indicates an infection.

What is TLC Test

White blood cells are also called leukocytes.

They are an important part of our immune system and help in fighting any infection or disease.

White blood cells have five parts

1) Neutrophils

2) Eosinophils

3) Basophils

4) Lymphocytes

5) Monocytes

Together these five make our leukocytes i.e. white blood cells.

In the TLC test, we see the total value of these five. When TLC is increased or decreased, it is a symptom of some diseases.

Why is TLC Test Done

TLC test is a part of Complete Blood Count (CBC) and it is done to detect the following diseases

1) Infection

2) Auto-Immune Disease

3) Any problem with blood

4) Weak immune system

5) Side effects of cancer treatment

6) Any problem in bone marrow

7) Inflammation in the body

What is the Normal Range for TLC Test

The normal value of TLC in our blood is 4,000 micro-liters to 11,000 micro-liters.

Being above or below this is a sign of disease.

Why TLC is Increased in the Body

TLC can increase due to many reasons like

1) Infection

2) Fever

3) In case of injury

4) Pregnancy

6) Being allergic to something

3) Body aches

4) Difficulty in breathing

5) Night sweats

7) Sudden weight loss

8) Wheezing

How is High TLC Treated

When the TLC is increased, the doctor first sees according to the symptoms whether there is any infection in the body or not.

If there is an infection, it is treated with antibiotics.

In most of the cases of increased TLC, infection is the main reason.

If there is no infection, then the doctor finds out other reasons and treats them.

What Does it Mean When TLC is Low

If TLC is low i.e. 2,000 or below then it can be due to the following reasons

1) Auto-Immune Disease

2) HIV or AIDS

3) Problem in bone marrow

4) Severe infection

5) Liver failure

6) Malfunction of spleen

7) Lump

8) Cancer

9) Side effects of cancer treatment

10) Due to excessive Alcohol

11) Causes of Malaria

12) Due to side effects of medicines

What are the Symptoms of Low TLC

If TLC is below 2,000 then the patient shows the following symptoms

1) Fever and chills

2) Swelling or redness in the body

3) Sores in the mouth

4) White or red blisters in the mouth

5) Hoarseness or throat infection

6) Coughing a lot

7) Difficulty in breathing

8) Pain while urinating

9) Diarrhea

Low TLC Count Treatment

When TLC is low, first of all, the doctor finds out its cause on the basis of symptoms and then treats it.

Low TLC can be a big problem.

When TLC is low, in most cases the doctor increases the number of TLC by injecting growth hormone injection.

If the TLC is low due to a serious infection, then the infection is first treated with antibiotics.

If there is any problem related to bone marrow or blood cancer, then you should consult a hematologist.

Many times the value of TLC also decreases due to malnutrition, then it gets cured by giving a nutritious diet.
