A CBC with differential is also known as a blood differential test, white blood differential count, or leukocyte differential count. It may be performed as part of a CBC test or as a follow-up to a CBC test that reveals you have an abnormally high white blood cell count.
What does high WBC in CBC mean?
White blood cell count.
If your white blood cell count is higher than normal, you may have an infection or inflammation. Or, it could indicate that you have an immune system disorder or a bone marrow disease. A high white blood cell count can also be a reaction to medication.
What does a CBC with diff test for?
A CBC with differential is used to help diagnose and monitor many different conditions, including anemia and infection. Also called blood cell count with differential.
What does a WBC differential indicate?
Differential; Diff; White blood cell differential count. The blood differential test measures the percentage of each type of white blood cell (WBC) that you have in your blood. It also reveals if there are any abnormal or immature cells. Basophils are a specific type of white blood cell.
When should I be worried about high WBC?
On its own, leukocytosis is usually not harmful. An abnormally raised white blood cell count is not a disease condition, but can point to another underlying cause such as infection, cancer or autoimmune disorders. An abnormally high white blood cell count should always be considered for its possible causes.
What is an abnormal CBC with differential?
Abnormal results of a CBC differential: Certain medical disorders can cause your bone marrow to produce abnormal counts of white blood cells. [1:1] Increased number of neutrophils: Your bone marrow may make a higher number of neutrophils if you have a bacterial infection or are experiencing acute stress or trauma.
What is the difference between a CBC and a CBC with differential?
There are five major types of white blood cells. A CBC test measures the total number of white cells in your blood. A test called a CBC with differential also measures the number of each type of these white blood cells.
Why would a doctor order a CBC Without differential?
They help your body fight infection. Platelets help your body clot. A CBC measures, counts, evaluates and studies many aspects of your blood: CBC without differential counts the total number of white blood cells.
What is WBC?
White blood cells are part of the body’s immune system. They help the body fight infection and other diseases. Types of white blood cells are granulocytes (neutrophils, eosinophils, and basophils), monocytes, and lymphocytes (T cells and B cells).
Does COVID-19 affect your white blood cell count?
WBC count at admission is significantly corelated with death in COVID-19 patients. Higher level of WBC count should be given more attention in the treatment of COVID-19.
On the other hand, if you have low levels of neutrophils (30%) and high levels of lymphocytes (60%), this is a sign that you have a viral infection. You should ask your doctor about your white blood cell differential, as it may tell you whether you have a bacterial infection or a viral infection.
Why is a differential WBC more valuable?
Why is a differential WBC count more valuable than a total WBC count when trying to pin down the specific source of pathology? A differential cound determines the relative percentage of each type of WBC. Increases or decreases in specific WBC populations are often indicative (diagnostic) of specific pathologies.
What is an alarming WBC count?
In general, for adults a count of more than 11,000 white blood cells (leukocytes) in a microliter of blood is considered a high white blood cell count.
What infections cause white blood cells to be high?
Advertisement
- Acute lymphocytic leukemia.
- Acute myelogenous leukemia (AML)
- Allergy, especially severe allergic reactions.
- Chronic lymphocytic leukemia.
- Chronic myelogenous leukemia.
- Drugs, such as corticosteroids and epinephrine.
- Infections, bacterial or viral.
- Myelofibrosis (a bone marrow disorder)
What medications cause high white blood cell count?
Drugs that may increase WBC counts include: Beta adrenergic agonists (for example, albuterol) Corticosteroids. Epinephrine.
Drugs that may lower your WBC count include:
- Antibiotics.
- Anticonvulsants.
- Antithyroid drugs.
- Arsenicals.
- Captopril.
- Chemotherapy drugs.
- Chlorpromazine.
- Clozapine.
What clues on a CBC would make a doctor suspect leukemia?
Leukemia is most often diagnosed through a diagnostic test called a complete blood count (CBC). If a patient’s CBC shows abnormal levels of white blood cells or abnormally low red blood cells or platelets, he or she has leukemia. The physician will then order a bone marrow biopsy to determine the type of leukemia.
What cancers are detected by blood tests?
What types of blood tests can help detect cancer?
- Prostate-specific antigen (PSA) for prostate cancer.
- Cancer antigen-125 (CA-125) for ovarian cancer.
- Calcitonin for medullary thyroid cancer.
- Alpha-fetoprotein (AFP) for liver cancer and testicular cancer.
What is a normal CBC differential?
In general, the reference ranges are: White blood cells: 4,500 to 11,000 cells per microliter (cells/mcL) Red blood cells: 4.5 million to 5.9 million cells/mcL for men; 4.1 million to 5.1 million cells/mcL for women. Hemoglobin: 14 to 17.5 grams per deciliter (gm/dL) for men; 12.3 to 15.3 gm/dL for women.
What is the purpose of doing a differential?
What is it used for? The blood differential test is used to diagnose a variety of medical conditions. These may include infections, autoimmune diseases, anemia, inflammatory diseases, and leukemia and other types of cancer.
How long does it take for WBC to return to normal?
Depending on the type of infection, WBC can take from 5 days to 25 days for levels to return back to normal. For instance, a study has found that patients who contracted COVID-19 took between 2 to 6 weeks after the onset of symptoms for their WBC count to return to normal.
How often should you have a CBC done?
Your doctor may recommend a CBC and BMP every year at your annual well visit. Other tests depend on your age, lifestyle and personal and family history. In most cases, your primary care provider will ask you to fast for 12 hours before your blood draw.
