How do I read my white blood cell count?
Normal white blood cell (WBC) count For men, a normal white blood cell count is anywhere between 5,000 and 10,000 white blood cells per μl of blood.
For women, it is a reading of between 4,500 and 11,000 per μl, and for children between 5,000 and 10,000..
What type of infections can a CBC detect?
The CBC can evaluate your overall health and detect a variety of diseases and conditions, such as infections, anemia and leukemia….Rare allergic reactions (hives, food allergy)Inflammation (rheumatoid arthritis, ulcerative colitis)Some leukemias.Uremia.
What is the most common reason for low white blood cell count?
A low white blood cell count usually is caused by: Viral infections that temporarily disrupt the work of bone marrow. Certain disorders present at birth (congenital) that involve diminished bone marrow function. Cancer or other diseases that damage bone marrow.
Can stress cause low white cell count?
In addition, stress decreases the body’s lymphocytes — the white blood cells that help fight off infection. The lower your lymphocyte level, the more at risk you are for viruses, including the common cold and cold sores.
What diseases do not show up in blood tests?
10 health conditions that can’t be diagnosed by blood testsDEMENTIA: It’s not your blood that gives the game away. … PARKINSON’S DISEASE: Again it is the symptoms — the shaking, stiffness and general slowing up — that make the diagnosis. … MULTIPLE SCLEROSIS (MS): You’ll probably end up having blood taken but that is to check for other problems which can look like MS.More items…
How long does CBC test results take?
CBC results are usually available to your doctor within 24 hours. Basic metabolic panel. This test measures common electrolytes in the blood as well as other compounds.
What is the normal percentage of lymphocytes in blood?
Normal Results Lymphocytes: 20% to 40% Monocytes: 2% to 8%
What is normal for white blood count?
The normal number of WBCs in the blood is 4,500 to 11,000 WBCs per microliter (4.5 to 11.0 × 109/L). Normal value ranges may vary slightly among different labs.
What does a blood test tell you?
Specifically, blood tests can help doctors: Evaluate how well organs—such as the kidneys, liver, thyroid, and heart—are working. Diagnose diseases and conditions such as cancer, HIV/AIDS, diabetes, anemia (uh-NEE-me-eh), and coronary heart disease. Find out whether you have risk factors for heart disease.
Can my doctor test my blood for drugs without telling me?
Lack of informed consent in clinical testing In many cases, such as trauma or overdose, explicit consent is not possible. However, even when substance abuse is suspected and the patient is able to provide consent, clinicians often order drug testing without the patient’s knowledge and consent.

Is lymphocytes 42 normal?
Lymphocytes normally represent 20% to 40% of circulating white blood cells. When the percentage of lymphocytes exceeds 40%, it is recognized as relative lymphocytosis.
Does a CBC check kidney function?
Decreased creatinine clearance may indicate decreased kidney function. Hemoglobin (part of a complete blood count or CBC)—may be done to detect anemia. The kidneys make a hormone called erythropoietin that controls red blood cell production and this may be affected by kidney damage.
What does a full blood test show?
Full blood count (FBC) This is a test to check the types and numbers of cells in your blood, including red blood cells, white blood cells and platelets. This can help give an indication of your general health, as well as provide important clues about certain health problems you may have.

What does abnormal test results mean?
Positive or abnormal, which means the disease or substance was found. Inconclusive or uncertain, which means there wasn’t enough information in the results to diagnose or rule out a disease. If you get an inconclusive result, you will probably get more tests.
What happens if CBC is abnormal?
Abnormal red blood cell, hemoglobin, or hematocrit levels may indicate anemia, iron deficiency, or heart disease. Low white cell count may indicate an autoimmune disorder, bone marrow disorder, or cancer. High white cell count may indicate an infection or reaction to medication.

What is a good lymphocyte level?
The normal lymphocyte range in adults is between 1,000 and 4,800 lymphocytes in 1 microliter (µL) of blood. In children, the normal range is between 3,000 and 9,500 lymphocytes in 1 µL of blood. Unusually high or low lymphocyte counts can be a sign of disease.
What is a high lymphocyte percentage?
Lymphocytes help fight off diseases, so it’s normal to see a temporary increase after an infection. A count significantly higher than 3,000 lymphocytes in a microliter of blood is generally considered to be lymphocytosis in adults. In children, the threshold for lymphocytosis varies with age.
What do my CBC results mean?
A complete blood count (CBC) is a blood test used to evaluate your overall health and detect a wide range of disorders, including anemia, infection and leukemia. A complete blood count test measures several components and features of your blood, including: Red blood cells, which carry oxygen.
