How do you interpret lab results?
How do you interpret lab results?
Lab results are often shown as a set of numbers known as a reference range. A reference range may also be called “normal values.” You may see something like this on your results: “normal: 77-99mg/dL” (milligrams per deciliter). Reference ranges are based on the normal test results of a large group of healthy people.
What are normal lab numbers?
Normal Laboratory Values
| Laboratory Test | Normal Range in US Units | Normal Range in SI Units |
|---|---|---|
| Marginal | 100-159 mg/dL | 2.59-4.14 mmol/L |
| High | 160-189 mg/dL | 4.14 – 4.89 mmol/L |
| Very High | >190 mg/dL | >4.91 mmol/L |
| Cholesterol, HDL | >60 mg/dL | >1.55 mmol/L |

What do abbreviations on blood tests mean?
Red blood cell values: RBC (red blood cell count): the number of red blood cells. HCT (hematocrit): the concentration of red blood cells in your blood (in other words, how much of your total blood is made up of red blood cells) MCV (mean corpuscular volume): the average size of your red blood cells.
What are good levels in a blood test?
Electrolytes
- Sodium. Normal blood sodium level is 135 – 145 milliequivalents per liter (mEq/L)
- Potassium. Normal blood potassium level is 3.5 – 5.0 (mEq/L)
- Bicarbonate. Normal serum range for bicarbonate is 22-30 millimoles per liter (mmol/L)
- Chloride. Normal serum range for chloride is 98 – 108 mmol/L.
What are the normal levels for sodium and potassium?
The mean baseline serum potassium and sodium levels were 4.47 ± 0.35 mEq/L and 142.67 ± 2.64 mEq/L, respectively. A total of 3.8% of participants had serum potassium level above the normal range (normal: 3.5–5.1 mEq/L), while 0.8% and 6.7% had lower and higher serum sodium level, respectively (normal: 136–146 mEq/L).
What is vitamin D listed as on a blood test?
Most vitamin D blood tests measure the level of 25(OH)D in your blood. Your kidneys use 25(OH)D to make “active vitamin D.” Active vitamin D lets your body use calcium to build bone and helps other cells work properly.
What does F mean on lab results?
The F value in regression is the result of a test where the null hypothesis is that all of the regression coefficients are equal to zero. In other words, the model has no predictive capability.
What are the blood test symbols?
Appendix B: Some Common Abbreviations
| Abbreviation | Stands for | More information |
|---|---|---|
| HCT | Hematocrit | A blood test measurement |
| HCV | Hepatitis C virus | A virus that causes one type of liver disease |
| HDL | High density lipoprotein | A type of cholesterol, also known as “good” cholesterol |
| HGB | Hemoglobin | A blood test measurement |
What is most important blood test?
Complete Metabolic and Lipid Panel This is the test you might receive at an annual physical. It’s valuable and low cost. Known as Complete Metabolic and Lipid Panel, this test reveals important information about the health of your vascular system, liver, kidneys, and blood cells.
What level of potassium indicates kidney failure?
Blood potassium >5.0 indicates potassium imbalance. Arbitrary thresholds are used to indicate degree of severity, such as mild (>5.0), moderate (>5.5), and severe (>6.0).
What lab values indicate dehydration?
With severe dehydration, the following laboratory studies are suggested: Serum sodium should be determined because hyponatremia (< 130 mEq/L) and hypernatremia (> 150 mEq/L) require specific treatment regimens.
What is the blood test for B12?
This test measures the level of B12 (also called cobalamin) found in your blood. Lower than normal levels of B12 may cause fatigue, muscle weakness, intestinal problems, numbness, memory loss, anemia, as well as irreversible nerve damage if left untreated.
What is Flag H in blood test?
If your blood counts fall outside of the normal range, which is shown in the “Reference interval” column, their values will be reported in the “Flag” column with an ‘L’ for low and an ‘H’ for high.
What does flag H mean on lab results?
A numeric result that is greater than the upper end of the reference interval will automatically flag as “H,” and a numeric result that is less than the lower end will automatically flag as “L.” Tests with a numeric result type for which no reference interval is defined in the LIS do not trigger any flags regardless of …

How do I read my lab test results?
Hemoglobin:Red blood cells can carry oxygen due to a protein called hemoglobin.
How to interpret labs?
Interpretation of Results . Test results are numbers until they are interpreted to give them meaning. The one test that arguably gives the most insight is the TSH. When used with the free T3 and free T4 tests, the TSH may even suggest the cause of any problem.
How to understand your lab results?
Store all test components according to the manufacturer’s instructions until ready for use.
