Why Do Different Labs Give Slightly Different Test Results? And How to Choose the Best Pathology Lab in Kolkata
Jul 10, 2026
Seeing two different numbers for the same test can be confusing! You may wonder ‘Which number is correct?’ Many patients have this question…so let’s look at how these differences occur and find out which pathology lab is right for you! If you are also confused about which one is the best pathology lab in Kolkata, you have reached the right place.
Why Pathology Tests Have Slightly Different Results
Lab reports can differ slightly for many reasons. Just like with baking a cake at different ovens (each has different temperatures), using different recipes (mixing ingredients) or using different equipment to make sure that cakes turn out the same; different laboratories will report results slightly differently due to particular variables that influence the final result. One issue causing the most differences between pathology labs in Kolkata relates to pre-analytic variables. The timing when a specimen is collected affects how it will be tested and ultimately affect the result. For example, when you fast (before having your glucose measured), your glucose level can vary significantly depending upon when you eat afterward. The type of tube used when a specimen is collected can affect how that blood sample is tested. And how the specimen is handled (the conditions or temperatures during transportation, temperature at which it’s stored, etc.) all contribute significantly to the pre-analytic phase of your laboratory analysis and are often the most important considerations affecting your results.
How the Differences Happen?
In cases of referral, general laboratories give report on assumptions, on the basis of one result. Suppose, in a lipid profile test, the HDL result came first, then the technicians assume and give probable numbers in the other tests. At AccuHealth these things are strictly prohibited. We examine each of the tests thoroughly. That’s why, people consider AccuHealth as the best pathology lab in Kolkata.
Identifying the Ideal Pathology Lab in Kolkata
When selecting a pathology lab in Kolkata, it is important to give this consideration as a priority since your health and well-being depend on having accurate lab results. Follow these guidelines to help you determine which pathology lab is right for you.
1. Verification of NABL Accreditation
NABL is the official laboratory accreditation body of India; non-negotiable is this requirement (ISO 15189:2022). NABL’s accreditation signifies that quality or competence is maintained throughout the laboratory. AccuHealth is an NABL accredited pathology lab in Kolkata.
2. The Laboratory’s Technology and Equipment
Automated analysers have been introduced into many modern labs. These have great potential for reducing human error. However, there are still other machines that are capable of analysing through electronic or mechanical means. The testing carried out by these machines per day usually have the ability to process thousands of results per hour and produce reliable and accurate outcomes. The best pathology lab in Kolkata invests heavily in state-of-the-art technology.
3. Turnaround Time:
While the ability to produce results quickly is important for parents and other patients’ peace of mind; however, you never want to sacrifice accuracy for quickness and should expect that both should be balanced nicely in a successful laboratory, and also be provided in a timely manner without the creation of a rush on your laboratory tests.
4. Evaluate Location & Access:
Look for a location that is accessible to you. By being able to collect samples from home, having multiple locations throughout your city will only help. AccuHealth has different centres at different locations, which are easily accessible to everyone.
5. Evaluate Customer Service:
Friendly staff members improve your experience, providing a more pleasant experience. Clear instructions are provided before testing explaining what you need to do to prepare for your tests; there is also responsive customer service available to answer any questions that you might have. Good labs will treat patients with dignity and respect.
6. Evaluate Price Transparency:
Hidden fees create a negative experience. The very best pathology in Kolkata provides you with an accurate price list before the test; therefore, you do not have to worry about finding out about additional fees after you have received treatment. The goal of providing quality, accurate tests, is to make them affordable.
