Normal blood levels vary significantly depending on the specific component being measured. There isn't one single "normal blood level." Instead, various blood components have their own reference ranges, and these ranges can also differ based on factors like age and sex.
Key Blood Components and Their Normal Ranges
The following table summarizes normal ranges for some common blood components, based on the provided reference Table 1Complete blood count:
| Blood Component | Abbreviation | Male Range | Female Range | Units |
|---|---|---|---|---|
| Red Blood Cells (RBCs) | RBC | 4.3-5.9 million/mm³ | 3.5-5.5 million/mm³ | million/cubic mm |
| Hemoglobin (HGB) | HGB | 13.5-17.5 g/dL | 12.0-16.0 g/dL | grams/deciliter |
| Hematocrit (HT) | HT | 41%-53% | 36%-46% | Percentage |
| Mean Corpuscular Volume (MCV) | MCV | 80-100 µm³ | 80-100 µm³ | cubic micrometers |
Important Note: These are just examples. Many other blood components are routinely measured, each with its own normal range. These ranges can vary slightly depending on the laboratory performing the test. Always consult your doctor or healthcare provider to interpret your blood test results. They will consider your individual health history and other factors when assessing whether your blood levels are within a healthy range.
Furthermore, other factors like blood oxygen levels (discussed in several of the provided links) are also crucial indicators of overall health, but their reference ranges are distinct from the values in the table above.
