Introduction
Welcome to our guide on how to get water out of ESR. ESR, or erythrocyte sedimentation rate, is a blood test that measures how quickly red blood cells settle in a test tube over an hour. A rise in ESR levels may indicate an inflammatory condition, infection, or cancer. It’s not uncommon for ESR tests to be ordered by doctors to diagnose medical conditions. However, it can be frustrating when the sample gets contaminated with water. Fortunately, there are ways to remove water from ESR samples effectively. In this article, we’ll guide you on how to get water out of ESR while maintaining the accuracy of the results.
What is ESR?
Before we dive into the steps on how to get water out of ESR, let’s first understand what ESR is. ESR stands for erythrocyte sedimentation rate, which measures the rate at which red blood cells settle in a test tube over time. When a sample is collected, a laboratory technician will place it in a test tube and wait for the red blood cells to settle to the bottom. The number of millimeters of red cells that fall within an hour is known as the ESR value. ESR values are typically elevated in the presence of inflammation or infection in the body.
Why is Water in ESR Samples a Problem?
Water in ESR samples is a problem because it can affect the accuracy of the results. Water in the sample can alter the ESR value, leading to inaccurate results. It can also interfere with the flow of the sample, making it difficult for the laboratory technician to read the results.
What Causes Water in ESR Samples?
Several factors can cause water in ESR samples, including:
| Cause | Description |
|---|---|
| Contaminated tube | If a tube is not properly cleaned and dried before use, it can introduce water into the sample. |
| Improper sample collection | If the needle used to collect the sample is wet or contaminated, it can introduce water into the sample. |
| Moisture in the air | In humid environments, moisture in the air can cause water droplets to form inside the tube. |
How to Get Water Out of ESR
Now that we’ve identified the causes of water in ESR samples let’s move on to the steps on how to get water out of ESR:
Step 1: Preparation
First, check the sample tube for any visible signs of water, such as droplets on the sides. If you notice water in the sample tube, do not proceed with the test. Instead, inform your doctor immediately and request a new test. If there are no visible signs of water, proceed to the next step.
Step 2: Centrifugation
Place the sample in a centrifuge and spin it at a high speed for at least 15-20 minutes. Centrifugation separates the red blood cells from the liquid component in the sample, allowing the water to settle at the bottom. Once the centrifugation is completed, use a pipette to remove the liquid component carefully, making sure not to disturb the settled water at the bottom of the tube.
Step 3: Re-suspension
Resuspend the red blood cells at the bottom of the sample tube carefully. Gently tilt the sample tube back and forth to mix the red blood cells with the remaining liquid component. Avoid shaking the sample tube vigorously, as this can introduce air bubbles, which can affect the accuracy of the results.
Step 4: Repeat Centrifugation
Repeat the centrifugation process for another 5-10 minutes. Centrifugation will help to ensure that the water has been removed from the sample effectively.
Step 5: Final Check
Once the centrifugation is completed, check the sample tube again for any visible signs of water droplets. If there are no visible signs of water, proceed with the ESR test.
Advantages and Disadvantages of Getting Water Out of ESR Samples
Advantages

FAQs
Can I still use the ESR sample if there is water inside?
No. Water in ESR samples can alter the ESR value, leading to inaccurate results.
What should I do if I notice water in my ESR sample?
Do not proceed with the test. Instead, inform your doctor immediately and request a new test.
Do I need special training to remove water from ESR samples?
Yes, removing water from ESR samples requires expertise and skills to perform the test correctly.
Can I use a regular centrifuge to remove water from ESR samples?
No. You need a specialized centrifuge that can spin the sample at a high speed to remove water effectively.
How long does it take to get water out of ESR samples?
The process of getting water out of ESR samples can take 30-40 minutes.
What happens if I don’t remove water from ESR samples?
Water in ESR samples can affect the accuracy of the results, leading to inaccurate diagnoses.
How often should I check for water in ESR samples?
Check for water in ESR samples every time you collect a sample.
What other tests can I do if my ESR sample has water in it?
You can request other blood tests, such as a C-reactive protein test, to evaluate inflammation in the body.
Can I prevent water from getting into ESR samples?
Yes. Ensure that the tube is clean and dry before use, and use proper sample collection techniques to prevent water contamination.
How much does it cost to remove water from ESR samples?
The cost of removing water from ESR samples varies, depending on the facility and location where you get tested.
What is the ideal temperature for storing ESR samples?
The ideal temperature for storing ESR samples is between 2°C to 8°C.
What is the ideal time to perform an ESR test?
The ideal time to perform an ESR test is early in the morning when inflammation levels are highest.
Can I interpret ESR test results on my own?
No. ESR test results should be interpreted by a trained medical professional.
Conclusion
In conclusion, water contamination in ESR samples is a common issue that can affect the accuracy of test results. However, by following the steps outlined in this article, you can remove water from ESR samples effectively while maintaining the accuracy of the results. Remember to check the sample tube for visible signs of water, use a specialized centrifuge, resuspend the red blood cells carefully, and double-check for any visible signs of water droplets before proceeding with the test. Removing water from ESR samples ensures that the results are accurate and reliable, which can help doctors diagnose medical conditions more accurately.
