Waiting for one’s blood test results can really be one of the most uneasy parts of going for any medical checkup.
Well, the honest truth is that it really just depends on the kind of test you did.
Some of the usual, routine blood tests can be ready very quickly, but others take a bit more time because of the specific analysis they need to do.
The lab also has its own process. We need to first handle your sample, then run the right analysis, and only after all that can we release the result.
Here at Inova Diagnostics, the time we say a test will be ready can vary from one test to another.
When you experience a delay in getting your blood test result, it might be because of the different analysis being carried out, depending on the type of test you did.
How Long Do Blood Test Results Usually Take?
The time it takes to get your blood test result really depends on:
- The specific type of test you are doing.
- The method used to check it.
- Whether it needs any extra steps or special processing.
- How busy the lab is at that moment.
- Whether we need to do any more tests on your sample.
For some everyday lab tests, the results can be available quickly once the analysis is completed. But for others, it just takes longer, plain and simple.
Why Do Some Blood Tests Take Longer Than Others?
The reason is that different tests are looking for different things in your body, and because of that, they might need different ways of checking them in the lab.
For routine blood tests, like a Full Blood Count, which we usually call an FBC or CBC, we are measuring a few important things in your blood, like red blood cells, white blood cells, haemoglobin, and platelets.
In Inova Diagnostics, we usually have the results for FBC testing ready within 12 to 24 hours.
However, when it comes to infection testing, labs can do different kinds of tests to check for infections.
Our infection screening includes tests for things like malaria, HIV, and hepatitis. For these, we usually provide results within 12 to 24 hours.
But remember, different infection tests use different methods, so it is always good to confirm the exact time for the specific test you have ordered.
For hormone testing, our turnaround time is normally 24 to 48 hours.
The testing can include tests for reproductive health, how your thyroid is working, and other hormone-related concerns.
But there are some important tests we call specialised testing. These tests might need extra laboratory processes or a confirmation step.
This is why they can take a bit longer than a regular, routine blood test.
So, if a lab scientist tells you one blood test will take longer than another, it does not necessarily mean there is a problem. It could just be because of the kind of test they are performing.
What Happens to Your Blood Sample After It Is Collected?
The blood collection itself might only take a few minutes, but the work in the laboratory continues long after you have left.
Simply put, the process generally goes like this:
- First, we collect your sample, then identify it properly and handle it carefully.
- After that, it goes for laboratory processing, then analysis, followed by quality checks, and finally, the result is reported.
The exact steps can depend on the specific test being done.
Your sample needs to be correctly identified and handled before we can perform the right test.
Once the laboratory analysis is fully done, the result can then be released according to our reporting process.
Can You Get Your Blood Test Results on the Same Day?
Sometimes, yes.
Again, it really depends on the specific test and the laboratory.
Some routine laboratory results can indeed be ready on the same day once they have been fully completed and finalised.
Lab tests like urinalysis are often available the same day once finalised in the system.
But let us not take this to mean every blood test will be ready the same day. That is just not how it works.
In Inova Diagnostics, you can always check our published timeframe for the particular test you had to get a better idea of when your result might be ready.
What Can Delay Blood Test Results?
If it takes longer than expected, it does not mean your result is abnormal.
There could be various reasons for a longer turnaround time. Maybe the test needs extra processing, or it is a more specialised test.
Perhaps confirmatory testing is needed, or the lab might even need to repeat part of the analysis.
Sometimes, the sample might need to be recollected because there was a problem with the specimen. Or it could just be related to the laboratory workflow.
The exact reason depends on the test and the laboratory itself.
What Does “Results Are Ready” Actually Mean?
There is an important distinction between a lab result simply being available and your doctor actually discussing that result with you.
Depending on how results are released, patients might sometimes see a result even before their doctor has had a chance to review it.
So, if you see a number or a result that you do not quite understand, avoid jumping to the worst conclusions immediately.
Your doctor is the best person to explain what that result means in relation to why the test was ordered and your own health history.
When Should You Follow Up If Your Results Are Delayed?
If we gave you a specific timeframe and you have not gotten your result after that period, then you can contact our laboratory or the healthcare provider who ordered the test for you.
When you reach out to us, it really helps if you have a few things handy:
- Your test information.
- The date your sample was collected.
- The name of the test.
- Any receipt or lab reference number you were given.
Frequently Asked Questions
How Long Does a Routine Blood Test Take?
The time depends on the specific test. At Inova Diagnostics, a Full Blood Count is currently listed as ready within 12 to 24 hours.
Can Blood Test Results Come Back the Same Day?
Yes. Some lab results can be available on the same day, but not every test has the same turnaround time.
Does a Delayed Blood Test Result Mean Something Is Wrong?
Not always. A delay can be related to the type of test, how the lab processes it, or whether it needs additional analysis.
How Long Do Hormone Blood Tests Take?
At Inova Diagnostics, you can see your results within 24 to 48 hours after your test.
Why Does One Blood Test Take Longer Than Another?
Different tests use different methods and might need different stages of processing. Some investigations are therefore completed faster than others.
Key Takeaways
- Every blood test has a specific timeframe for when you can expect your results.
- Routine tests might be ready relatively quicker than others.
- Tests that require special analysis can take much longer.
- A delayed result does not mean that the result is abnormal.
- The time it takes to process a test and the time your doctor needs to interpret it are not necessarily the same thing.
Conclusion
Waiting for a blood test result can definitely be stressful, especially when you are not even sure how long you are supposed to wait.
The time truly depends on the particular test and the laboratory doing the work.
Here at Inova Diagnostics, our published times range from within 12 hours for urinalysis and cultures to 48 to 72 hours for stool microscopy and sensitivity.
For common blood tests like FBC, they are mostly ready within 12 to 24 hours.
