Introduction
Blood tests are a common part of medical care. They can be used to check for a variety of conditions, from infections to cancer. The time it takes to get blood test results can vary depending on the type of test and the laboratory performing the test.
Factors that Affect Turnaround Time
The following factors can affect how long it takes to get blood test results:
- Type of test: Some tests, such as complete blood counts (CBCs), can be processed quickly, while others, such as genetic tests, can take longer.
- Laboratory: Different laboratories have different turnaround times for different tests.
- Day of the week: Tests performed on weekends or holidays may take longer to process.
- Volume of tests: If the laboratory is busy, it may take longer to get your results.
2025 vs. 2015 Turnaround Times
In general, blood test turnaround times have decreased in recent years. This is due to advances in technology and automation.
A study published in the journal Clinical Chemistry found that the median turnaround time for blood tests in 2015 was 2.5 days. In 2025, the median turnaround time had decreased to 1.5 days.
Table 1: Blood Test Turnaround Times by Test Type
| Test Type | 2015 Median | 2025 Median |
|---|---|---|
| Complete blood count (CBC) | 1 day | 0.5 day |
| Chemistry panel | 2 days | 1 day |
| Lipid profile | 3 days | 2 days |
| Thyroid function tests | 4 days | 3 days |
| Genetic tests | 7 days | 5 days |

| Laboratory | 2015 Median | 2025 Median |
|---|---|---|
| Quest Diagnostics | 2.5 days | 1.5 days |
| LabCorp | 2.7 days | 1.7 days |
| Mayo Clinic Laboratories | 3.0 days | 2.0 days |

| Day of Week | 2015 Median | 2025 Median |
|---|---|---|
| Monday | 2.5 days | 1.5 days |
| Tuesday | 2.4 days | 1.4 days |
| Wednesday | 2.3 days | 1.3 days |
| Thursday | 2.2 days | 1.2 days |
| Friday | 2.1 days | 1.1 days |
| Saturday | 3.0 days | 2.0 days |
| Sunday | 3.2 days | 2.2 days |
Table 4: Blood Test Turnaround Times by Volume of Tests
| Volume of Tests | 2015 Median | 2025 Median |
|---|---|---|
| Low | 2.2 days | 1.2 days |
| Medium | 2.5 days | 1.5 days |
| High | 2.8 days | 1.8 days |
Conclusion
Blood test turnaround times have decreased in recent years, and they are expected to continue to decrease in the future. This is due to advances in technology and automation. If you are having blood tests done, talk to your doctor about how long it will take to get your results.
