11 Things to Keep in Mind for a Lab Test

Lab tests are essential diagnostic tools that provide valuable information about a person’s health. Whether you are getting a routine blood test or a more specialized test, there are several things to keep in mind to ensure the most accurate and reliable results.

With the current technological advancement, you can prevent several diseases by diagnosing them at the right time. So, be completely ready for your lab test for accurate results.

If you want to take a lab test to identify your health concerns, you are at the right place. Here are a few things to consider before going for a lab test:

  • Follow Complete Instructions

One of the most crucial things to remember for a lab test is to carefully follow all instructions given by your healthcare provider or the lab technician. These instructions may include dietary restrictions, medication requirements, and specific pre-test preparations.

It is essential to follow these instructions as they can affect the accuracy and reliability of the test results. Failing to follow the instructions can cause complications in your health and affect the efficiency of the results.

  • Be Aware of Insurance Coverage

Lab tests can be expensive. Therefore, you need to be aware of your insurance coverage and any out-of-pocket costs you may be responsible for. Make sure to get your tests done from a reputable lab that the government approves.

You can also customize your test to adjust with your specific requirements, prices, and availability. For example, Ulta lab tests allow you to take control over your healthcare costs and customize your lab testing experience by ordering lab tests online, get it done at a nearby healthcare center, and then track the results online.

  • Drink Plenty of Water

Staying hydrated can help make it easier to draw blood and can also help prevent any complications from the test. Adequate hydration can help improve the accuracy of certain tests, such as blood tests, by making it easier for the lab technician to find a vein and collect the blood sample.

Additionally, drinking water can help flush out any substances in your system that may interfere with the accuracy of the test results. Keep a water bottle with you, especially for a blood or urine test.

  • Avoid Consuming Alcohol

Another important thing to keep in mind when preparing for a lab test is to avoid consuming alcohol before the test. Alcohol can interfere with the accuracy of certain lab tests, including liver function and blood alcohol tests.

Consuming alcohol before the test can produce false positive or negative results. For instance, alcohol consumption can elevate liver enzyme levels, falsely indicating liver damage or disease on a liver function test.

  • Avoid Strenuous Exercise

Avoiding strenuous exercise 24 hours before the test is crucial. Strenuous exercise can affect certain lab test results, including blood tests and urine tests.

Intense physical activity can cause muscle damage and inflammation, leading to elevated levels of certain enzymes and proteins in the blood. It can result in false positive results on some lab tests, like liver function or Creatine kinase tests.

  • Communicate Clearly

Certain medications can affect lab test results. Make sure to inform your healthcare provider of any medications you are on. Some medications can also affect the body’s normal functioning, leading to changes in blood composition and other physiological functions.

It is essential to inform your doctor or lab technician of any prescription or over-the-counter medications, vitamins, supplements, or herbal remedies you take.

  • Fast if Required 

If fasting is required for your test, make sure to follow the fasting instructions carefully. It may include not eating or drinking anything except water for a certain period before your test.

Typically 8-12 hours of fasting before the test are enough. However, if there are special instructions from your healthcare provider to increase or decrease the fasting period, then make sure to follow that.

  • Wear Comfortable Clothing

You should wear comfortable clothing that enables easy access to the area of the body being tested. For example, if you are getting a blood test, wear a short-sleeved shirt or a shirt with sleeves that can be rolled up easily.

Wearing comfortable clothing also helps to reduce stress and anxiety, which can affect the test results. You may feel more relaxed and at ease when wearing comfortable and familiar clothing rather than tight, restrictive, or uncomfortable clothes.

  • Stay Calm

Try to stay relaxed and calm during the test. It can help make the process go more smoothly and can also help prevent any complications. In addition, some lab tests may require you to remain still or lie down for an extended time.

Being comfortable and relaxed can make this experience less uncomfortable and more tolerable. If you feel nervous, try taking deep breaths, listening to calming music, or engaging in other relaxation techniques.

  • Be Prepared for Possible Side Effects

Some lab tests may cause side effects such as dizziness, lightheadedness, or nausea. Make sure to inform the lab technician or your doctor if you experience such changes.

In some cases, the patient may experience more serious side effects. For example, in case of an allergic reaction to a medication used during the lab test, you may experience difficulty breathing, swelling, or hives. If you experience these symptoms, consult with your doctor immediately.

  • Follow Up on Time

After your lab test, ensure to follow up with your healthcare provider to discuss the results and any necessary next steps.

Do not hesitate to contact your healthcare provider if you have any questions regarding your lab test results. They can help you understand what the results mean and provide guidance on any further steps that need to be taken.



Lab tests are an important diagnostic tool that can provide valuable information about a person’s health. By following these tips, you can help ensure the most accurate and reliable results from your lab test.

Always follow all the instructions, stay hydrated, avoid alcohol and strenuous exercise, inform your healthcare provider of any medications, wear comfortable clothing, stay relaxed, be prepared for possible side effects, follow up with your healthcare provider, and be aware of insurance coverage.
