TEC, AEC Test: A Complete Guide, Price, Preparation

If you are suffering from chronic itchiness, recurrent allergies, skin allergic rashes, sneezing, or some breathing difficulties, the doctor might order you a Total Eosinophil Count (TEC) test. This is a basic blood test that finds out the amount of eosinophils present in your blood.

Eosinophils belong to the white blood cells and are responsible for fighting the body's foreign agents. Their major role is to mediate allergic reactions and to protect the body from some parasitic infections. Eosinophils can be found in the blood in smaller amounts during a healthy state and increase in certain conditions.

At City Imaging, we are of the opinion that knowledge regarding your diagnostic tests can ease testing anxiety. The price of Total Eosinophil Count ranges from INR 150 to INR 400.

What is the Total Eosinophil Count?

The Total Eosinophil Count (TEC), Also know as Absolute Eosinophil Count (AEC), is a laboratory investigation performed to analyse the total count of eosinophils present in the blood of the patient. The eosinophils form one type of white blood cell along with four other subtypes of white blood cell. The function of eosinophils is to help in the fight against various infections, allergens and inflammatory conditions.

Under ordinary circumstances, eosinophils account for only a small percentage of the total white blood cells. When the body is assaulted by certain factors, however, the quantity and activity of eosinophils may rise considerably. TEC test helps in identifying the actual number of eosinophils rather than simply calculating their percentage out of the total number of white blood cells in the body. This is helpful for medical practitioners in assessing disorders in which eosinophils play a role.

Why is a Total Eosinophil Count Test done?

A physician may suggest that a TEC test should be performed when a patient already exhibits signs of an allergic reaction or has a medical history that indicates such a condition:

• Persistent or unexplained itching
• Skin rashes
• Frequent sneezing
• Certain types of asthma
• Suspected parasitic infections
• Recurrent allergic symptoms
• Unexplained increases in eosinophils on a CBC
• Monitoring certain eosinophil-related conditions
• Evaluation of unexplained inflammation or symptoms

What are Eosinophils?

Eosinophils are white blood cells that are mainly produced in the bone marrow. These cells can travel and migrate to tissues according to the needs of the immune system.

These cells have several immune functions, including helping to fight some parasites in the body. Eosinophils can be higher than normal in patients who

How is the TEC Test performed?

The sample is analysed to assess the Total Eosinophil Count. A health professional will draw a small amount of blood from one of the veins in the patient’s arm. The sample will then be placed in an appropriate container and sent for testing. After the process is complete, the patient may resume their activities, unless instructed otherwise by their doctor.

What does a high Eosinophil Count mean?

There are various possible causes of eosinophilia, the most common being allergic diseases. Parasitic infections may also increase eosinophils, especially in cases of certain tissue-dwelling parasites.

Additionally, some medication reactions, inflammatory diseases, and some blood and immune diseases may also be responsible for eosinophilia. Therefore, the increased TEC does not indicate any specific disease.

What does a low Eosinophil Count mean?

As far as medical science is concerned, a low eosinophil count is not that alarming compared to greatly raised eosinophil count. Eosinophil counts can vary fairly and a low count can occur for instance, due to stress or some medicine. For example, corticosteroids can lower eosinophils.

A low eosinophil count is usually not a serious health condition by itself. The meaning of low eosinophil count depends on the whole blood count and some factors like illness, medicine and personal medical history.

What is the relation between TEC Test and Asthma?

Certain categories of asthma are linked with higher levels of eosinophils. Eosinophil tests can therefore be useful in determining the type of inflammation present in such cases.

The eosinophil test alone cannot provide a diagnosis of asthma. Physicians can use the results of eosinophil tests together with symptoms, lung function tests, medical history, and other forms of investigation for assessment of respiratory issues.

What are the medicines that can affect Eosinophil Levels?

Certain medicines can modify eosinophil levels. Some drugs can trigger eosinophilia as an adverse reaction while corticosteroids can decrease eosinophils. That is why it is essential to inform your physician about all the prescribed ones, over-the-counter medications, and supplements you are taking. Don't stop taking a prescribed drug just because you are undergoing a TEC test. If it is necessary to stop or substitute the drug, your physician will give appropriate instructions.
