A normal platelet count generally ranges from 150,000 to 450,000 platelets per microliter (mcL) of blood for most adults. However, specific ranges can vary slightly depending on age and sex, although many sources cite a broad range regardless of age.
Platelet Count Ranges by Age Group (Approximate):
The following data is based on available information and may vary slightly depending on the source: Note that these are approximate ranges, and individual variations are normal. A doctor should always be consulted for interpretation of any blood test results.
- Broad General Range (Adults & many children): 150,000 - 450,000 platelets/mcL.
- Children (Age 5-17): While a precise breakdown by age within this group isn't universally agreed upon across all sources, the range tends to be within the broad adult range, although some studies may show slightly different values for younger children.
- Specific Examples from One Source (Note: This varies across sources):
- Ages 5-9: Around 310,000 (males), slightly less for females.
- Ages 10-14: Around 280,000 (males), slightly more for females.
- Ages 15-17: 250,000 (males), 270,000 (females).
- Ages 18-34: 240,000 (males), 265,000 (females).
Important Considerations:
- Individual Variation: The provided ranges are averages. A platelet count slightly outside these ranges doesn't necessarily indicate a problem.
- Medical Consultation: Always consult a healthcare professional to interpret your or your child's platelet count. They can consider other factors to assess your overall health.
- Age-Specific Ranges: While the broad range is often cited as applicable to most age groups, some research suggests slightly different ranges for specific age groups, particularly for children and the elderly. It is recommended to always consult a physician when addressing blood test results.
