How Long Do Blood Test Results Take?



Blood tests provide valuable information about our health, but we often wonder how long it takes to receive the results. The time frame for getting blood test results can vary depending on various factors.

In this blog, we will delve into the factors influencing the turnaround time of blood test results, the types of blood tests with different processing times, and what you can do to expedite the process.

Factors Affecting Turnaround Time:

  1. Type of Test: Different blood tests have different processing requirements. Some tests can be completed quickly, while others may take more time due to the complexity of the analysis.
  2. Laboratory Efficiency: The efficiency of the laboratory conducting the tests plays a significant role in the result turnaround time. Well-equipped and staffed laboratories can process tests faster.
  3. Sample Transportation: The time it takes to transport the blood sample from the collection center to the laboratory can impact the overall turnaround time.

Types of Blood Tests and Their Turnaround Times:

1. Complete Blood Picture (CBC)

  • Turnaround Time: Usually the results for CBP test comes within a few hours to a day.
  • Purpose: Measures the levels of various blood components, including red blood cells, white blood cells, and platelets, to evaluate overall health and detect conditions such as anemia or infection.

2. Blood Glucose Test

  • Turnaround Time: Results for blood glucose test is available within the same day to 24 hours.
  • Purpose: Measures blood sugar levels to diagnose diabetes or monitor glucose control in individuals with diabetes.

3. Lipid Profile

  • Turnaround Time: Results for lipid profiles come usually within a day.
  • Purpose: Measures cholesterol levels (including LDL, HDL, and triglycerides) to assess cardiovascular health and risk of heart disease.

4. Complex Panels: Comprehensive panels assessing multiple markers, such as liver and kidney function tests, may take a few days to a week for complete analysis.

5. Specialized Tests: Tests for specific conditions or rare diseases might require specialized equipment and expertise, leading to longer turnaround times.

6. Basic Metabolic Panel (BMP)

  • Turnaround Time: Typically within a day.
  • Purpose: Measures electrolytes, glucose, and kidney function markers to assess basic metabolic health and detect conditions such as diabetes or kidney disease.

7. Comprehensive Metabolic Panel (CMP)

  • Turnaround Time: Typically within a day.
  • Purpose: Similar to BMP but also includes liver function markers to evaluate overall metabolic and liver health.

8. Pregnancy blood test

Pregnancy blood tests, unlike urine tests, can detect pregnancy very early and offer a more accurate result. However, the wait for results can vary depending on a few factors:

Type of Blood Test: There are two main types of pregnancy blood tests:

  • Qualitative hCG test: This simple test detects the presence of the pregnancy hormone (hCG) and provides a yes/no answer on pregnancy. Results are typically faster, within a few hours to a day.
  • Quantitative hCG test: This test measures the exact amount of hCG present, which can be helpful for dating the pregnancy or monitoring its progress. Results for this test may take longer, anywhere from 1 to 2 days.

9. Thyroid tests

Basic Thyroid test results usually take around 24 to 48 hours to come back after the blood sample is collected.  More specialized tests might require an external reference lab, taking closer to 3 days.

10. Cancer tests

The time it takes for cancer test results to come back can vary widely depending on several factors. In general, cancer test results may take anywhere from a few days to a few weeks to come back. 

Here’s a rough time frame based on test type:

  • Blood Tests: A few days
  • Biopsy/Cytology: Several days to a week
  • Advanced Tests: Up to 2-3 weeks

11. Sexually transmitted infection (STI) tests

Type of Test

  • Rapid Tests: These tests, often available for HIV, can provide results in as little as 15-30 minutes.
  • Standard Tests: These encompass most other STIs and are typically sent to a lab for analysis. Results for these can take anywhere from 1 to 3 days.

12. Anemia tests

The wait for anemia test results typically falls on the shorter side compared to some other tests. Here’s a breakdown of what to expect:

  • Relatively Fast Results: Anemia tests, often involving a complete blood count (CBC) or hemoglobin and hematocrit (H&H) test, are frequently analyzed on-site at a hospital lab. This allows for a quicker turnaround time, with results potentially coming back within a few hours.
  • Rapid Tests Available: In some cases, rapid tests for anemia might be used, providing results in as little as minutes.

Expedite the Process:

Communicate with Your Healthcare Provider: Discuss the urgency of your test results with your healthcare provider. They may be able to prioritize certain tests if necessary.

  1. Follow-Up: If you haven’t received your results within the expected timeframe, don’t hesitate to follow up with your healthcare provider or the testing facility.
  2. Online Portals: Many healthcare providers offer online lab test booking portals where you can access your test results once they become available.


Understanding the factors influencing the turnaround time of blood test results can help manage expectations and reduce anxiety while waiting for results. While some tests yield quick results, others may take longer due to complexity. Clear communication with your healthcare provider and the testing facility can expedite the process and provide you with timely insights into your health status. Remember that prompt access to your test results enables early intervention and proactive healthcare management.
