What does it mean to interpret lab results?

Spread the love

Interpretation of a laboratory result requires that the result can be related to a relevant reference value. This can be the same patient’s earlier results, if this is possible, or be done by comparing to data from a “normal” population.

How do you read a lab report?

  1. Negative or normal, which means the disease or substance being tested was not found.
  2. Positive or abnormal, which means the disease or substance was found.

How do you analyze chemicals?

The main steps that are performed during a chemical analysis are the following: (1) sampling, (2) field sample pretreatment, (3) laboratory treatment, (4) laboratory assay, (5) calculations, and (6) results presentation. Each must be executed correctly in order for the analytical result to be accurate.

What do lab values tell you?

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 presence of any underlying condition(s).

How do you read a CBC lab report?

When you get your report, you’ll see two columns: a “reference range” and your results. If your results are inside the reference range, they’re considered normal. If your results are higher or lower than the reference range, they’re abnormal.

What are the normal ranges for blood test results?

  • 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 conclusion can you make from the result of your experiment?

Your conclusions summarize how your results support or contradict your original hypothesis: Summarize your science fair project results in a few sentences and use this summary to support your conclusion. Include key facts from your background research to help explain your results as needed.

What does TNP mean in lab results?

Introducing the Test Not Performed (TNP) Report.

Why are lab results important?

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.

What is the analysis in chemistry?

An analysis provides chemical or physical information about a sample. The component in the sample of interest to us is called the analyte, and the remainder of the sample is the matrix. In an analysis we determine the identity, the concentration, or the properties of an analyte.

What is the qualitative analysis in chemistry?

qualitative chemical analysis, branch of chemistry that deals with the identification of elements or grouping of elements present in a sample. The techniques employed in qualitative analysis vary in complexity, depending on the nature of the sample.

What are the two major types of chemical analysis?

  • Qualitative analysis – used to find out if a substance is present in a sample. An example of this type of analysis is the flame test.
  • Quantitative analysis – used to find out how much of a substance is in a sample. These tests produce numbers in their results.

What lab values would indicate infection?

Neutrophils 1,500-8,000/mm3 Increase in bacterial infections, hemorrhage, diabetic acidosis. Absolute Neutrophil Count (ANC) <1,000/mm3: patient at increased risk for infection.

What lab values are most important?

Here are important lab values for the complete blood count test: Red Blood Cells: Men- 4.32 – 5.72 million cells/ mcL; Women- 3.90 – 5.03 million cells/ mcL. White Blood Cells: 3500 – 9600 cells/ mcL. Platelets: Men- 135,000 – 317,000 cells/ mcL; Women- 157,000 – 371,000 cells/ mcL.

What are examples of lab values?

  • Partial pressure of oxygen (PaO2): 75 – 100 mmHg.
  • Partial pressure of carbon dioxide (PaCO2): 38 – 42 mmHg.
  • Arterial blood pH: 7.38 – 7.42.
  • Oxygen saturation (SaO2): 94 – 100%
  • Bicarbonate – (HCO3): 22 – 28 mEq/L.

What does high RBC mean?

Definition. By Mayo Clinic Staff. A high red blood cell count is an increase in oxygen-carrying cells in your bloodstream. Red blood cells transport oxygen from your lungs to tissues throughout your body.

What if neutrophils are high?

Neutrophils help you fight infection. But sometimes, your neutrophils stay in the fight longer than necessary. If your bloodstream is teeming with too many neutrophils, you may develop leukocytosis or a high total white blood cell count. You may have symptoms such as fevers or recurring infections.

What does WBC mean in a blood test?

A white blood count measures the number of white cells in your blood. White blood cells are part of the immune system. They help your body fight off infections and other diseases. When you get sick, your body makes more white blood cells to fight the bacteria, viruses, or other foreign substances causing your illness.

What cancers are detected by blood tests?

  • Hodgkin lymphoma.
  • Leukemia.
  • Non-Hodgkin lymphoma.
  • Multiple myeloma.

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.

How do you summarize an experiment?

State the research question and explain why it is interesting. State the hypotheses tested. Briefly describe the methods (design, participants, materials, procedure, what was manipulated [independent variables], what was measured [dependent variables], how data were analyzed. Describe the results.

How do you write a conclusion for a chemistry lab report?

When writing a conclusion you should: briefly restate the purpose of the experiment (i.e. the question it was seeking to answer) identify the main findings (i.e. the answer to the research question) note the main limitations that are relevant to the interpretation of the results.

How do you conclude a lab report?

  1. Restate the Experiment’s Goals. Begin your conclusion by restating the goals of your experiment.
  2. Describe Methods Used. Provide a brief summary of the methods you used in your experiment.
  3. Include and Analyze Final Data.
  4. State Whether Your Experiment Succeeded.

What does a positive test look like?

Two lines – even faint lines – indicate the test is positive.

What does flu A TNP mean?

TNP (test not performed): the sample could not be processed for technical reasons, most often because too much mucous was on the swab.
