What type of wbc is elevated in an acute infection
Symptoms of infection include:. Symptoms of inflammation and autoimmune diseases will be different, depending on the area of inflammation and type of disease. You may also need this test if you have a disease that weakens your immune system or are taking medicine that lowers your immune response. If the test shows your white blood count is getting too low, your provider may be able to adjust your treatment. Your newborn or older child may also be tested as part of a routine screening, or if they have symptoms of a white blood cell disorder.
A health care professional will take a blood sample from a vein in your arm, using a small needle. After the needle is inserted, a small amount of blood will be collected into a test tube or vial. You may feel a little sting when the needle goes in or out.
To test children, a health care provider will take a sample from the heel newborns and young babies or the fingertip older babies and children. The provider will clean the heel or fingertip with alcohol and poke the site with a small needle. The provider will collect a few drops of blood and put a bandage on the site. After a blood test, you may have slight pain or bruising at the spot where the needle was put in, but most symptoms go away quickly.
There is very little risk to your baby or child with a needle stick test. Your child may feel a little pinch when the site is poked, and a small bruise may form at the site. This should go away quickly.
If you are already being treated for a white blood cell disorder, your results may show if your treatment is working or whether your condition has improved. Learn more about laboratory tests, reference ranges, and understanding results. White blood count results are often compared with results of other blood tests, including a blood differential. A blood differential test shows the amount of each type of white blood cell, such as neutrophils or lymphocytes. Neutrophils mostly target bacterial infections.
Lymphocytes mostly target viral infections. The information on this site should not be used as a substitute for professional medical care or advice. Differential leukocyte count diff - peripheral blood.

Medical Tests. Definition The blood differential test measures the percentage of each type of white blood cell WBC that you have in your blood. In some cases, all white blood cells become affected.
However, some people have a specific disease in which only one type of white blood cell is affected. If levels of one particular type of white blood cell increase, this may be due to a specific trigger:. There is, on occasion, no identifiable cause for the increase in white blood cells.
This is known as idiopathic hypereosinophilic syndrome. It can lead to serious complications, such as damage to the heart, lung, liver, skin, and nervous system. White blood cell levels increase significantly during healthy pregnancy because of the physical stress the body endures during this time.
The levels start to rise within the first trimester and continue to rise into the third trimester. During labor and in the hours following delivery, white blood cell levels may surge again, to between 9, and 25, white blood cells in every microliter of blood.
This is in response to the physical stresses and trauma of labor. Within 6—8 weeks of delivery, white blood cells return to their normal levels. A doctor may use a blood test to determine levels of white blood cells. If levels of white blood cells are lower than usual, this may be a sign that the person has reduced immune activity.
This can occur as a result of conditions similar to HIV , or immunosuppressant medications. A deficiency of white blood cells is why people with conditions or medications that suppress the immune system have an increased risk of infection. A number of conditions, collectively known as myeloproliferative disorders, can occur in the bone marrow.
These develop when too many immature blood cells are produced, leading to an imbalance. Myeloproliferative disorders are rare conditions that may or may not become malignant. The exact effects of a high white blood cell count depend on the condition or factor causing them.
After noting any symptoms, a doctor can use a blood test to assess the white blood cell count, and further tests and examinations will often be necessary to pinpoint the exact cause of the problem. A high white blood cell count may indicate several things, such as the immune system is working to destroy an infection, a sign of physical or emotional stress, or particular types of cancer.
Pregnancy also leads to high white blood cell count, as levels tend to rise from the first trimester, into the third.
