How are reference ranges for blood tests determined?
Reference ranges are determined by the individual laboratory performing the test taking into account factors such as age, gender, race, etc. It is the responsibility of every laboratory to verify the reference ranges of every analyte they report.
What is reference range negative?
For example, a healthy person’s test result would not detect COVID-19, so the reference range would be “negative” or “not detected.” If your test result shows a value of “positive” or “detected,” that falls outside of the reference range and would be considered abnormal or atypical.

What reference range means?
How do you find the reference range?
When assuming a normal distribution, the reference range is obtained by measuring the values in a reference group and taking two standard deviations either side of the mean. This encompasses ~95% of the total population.
Why are blood test reference ranges different?
Reference ranges for the same methods or instruments may differ between laboratories and geographic areas for the following reasons: Operating conditions are different. Criteria for selection of healthy subjects are different. Patient populations are different.
How do you interpret hematology results?
The RBC count is useful for determining such problems as anemia and hemorrhage. In combination with other hematology tests, it can be quite useful for diagnosis….Test: Total Hemoglobin (Hgb or Hb)
| Percentage of total Hemoglobin | hemoglobin | Clinical Implications |
|---|---|---|
| Homozygous Hb C | 90% to 98% | Hb C disease |
