Lab values are used to determine a patient’s overall health and well-being. There are many factors that can affect a patient’s result and lab values but some of the most common factors are gender, age, race, the medicines taken, and the presense of any underlying condition(s).
What are important lab values?
Laboratory Reference Ranges in Healthy Adults
- Ammonia: 15-50 µmol/L.
- Ceruloplasmin: 15-60 mg/dL.
- Chloride: 95-105 mmol/L.
- Copper: 70-150 µg/dL.
- Creatinine: 0.8-1.3 mg/dL.
- Blood urea nitrogen: 8-21 mg/dL.
- Ferritin: 12-300 ng/mL (men), 12-150 ng/mL (women)
- Glucose: 65-110 mg/dL.
What do abnormal lab values 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.
Why do nurses need to know lab values?
Diagnostic lab tests help determine a patient’s condition, therefore it is important for nurses to be knowledgeable about the different tests and their values in order to make informed clinical decisions.
What is the importance of lab testing?
Laboratory tests are often part of a routine checkup to look for changes in your health. They also help doctors diagnose medical conditions, plan or evaluate treatments, and monitor diseases.
Why lab test is important?
Medical laboratory testing plays a crucial role in the early detection, diagnosis and treatment of disease in patients. If a patient routinely submits to lab testing, this may allow doctors to respond swiftly with preventative treatment, which could save the patient time, money, and possibly sickness in the future.
What do 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.
What does flag l mean on a blood test?
Flags: for paper results
There is often an empty column with marks identifying which rows contain abnormal bloodwork results. The mark may be an asterisk, or an “H” for high or “L” for low or “A” for abnormal. In this printout, normal results are indicated with an “N”.
What does morph positive mean in a blood test?
Positive values indicate percentage morphed to the same-sex, whereas negative values indicate percentage morphed to the opposite-sex. Error bars indicate standard errors of the mean.

What are the 6 main reasons for laboratory testing?
Reasons for Ordering a Laboratory Test
- Diagnosis (to rule in or rule out a diagnosis).
- Monitoring (eg, the effect of drug therapy).
- Screening (eg, for congenital hypothyroidism via neonatal thyroxine testing).
- Research (to understand the pathophysiology of a particular disease process).
What happen if white blood cells are high?
Produced in your bone marrow, they defend your body against infections and disease. But, when there are too many white blood cells, it usually means you have infection or inflammation in your body. Less commonly, a high white blood cell count could indicate certain blood cancers or bone marrow disorders.
What type of infections can a CBC detect?
Some of the most common diseases a CBC detects include anemia, autoimmune disorders, bone marrow disorders, dehydration, infections, inflammation, leukemia, lymphoma, myeloproliferative neoplasms, myelodysplastic syndrome, sickle cell disease, thalassemia, nutritional deficiencies (e.g., Iron, B12 or folate), and
What does it mean when your blood test shows inflammation?
Blood tests known as ‘inflammatory markers’ can detect inflammation in the body, caused by many diseases including infections, auto-immune conditions and cancers. The tests don’t identify what’s causing the inflammation: it might be as simple as a viral infection, or as serious as cancer.
What does H stand for in blood test?
H and H: H and H, sometimes written as “H&H”, is a popular shorthand for hemoglobin and hematocrit, two very common and important blood tests. Hemoglobin is the oxygen-carrying protein pigment in the blood, specifically in the red blood cells.
What Flag H means?
• A flag, as applicable (available flags include. H [high], L [low], A [abnormal], and C [critical]) • Additional interpretive comments and/or footnotes, as. applicable.
What does H mean on a blood test?
Abnormal test results.
For example, “H” next to a result may mean that it is higher than the reference range. “L” may mean “low” and “WNL” usually means “within normal limits.”
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 means hematocrit?
A hematocrit (he-MAT-uh-krit) test measures the proportion of red blood cells in your blood. Red blood cells carry oxygen throughout your body. Having too few or too many red blood cells can be a sign of certain diseases. The hematocrit test, also known as a packed-cell volume (PCV) test, is a simple blood test.
What is lymphocytes in hematology?
Lymphocytes are a type of white blood cell. They play an important role in your immune system, helping your body fight off infection. Many underlying medical conditions can cause lymphocytosis. High lymphocyte blood levels indicate your body is dealing with an infection or other inflammatory condition.
