Choosing the best diagnostic centre isn’t just about picking the one closest to your home. It’s about getting accurate results, on time, to avoid unnecessary stress and health issues. Imagine needing to repeat tests because of an error or waiting days for results you urgently need. It’s not just inconvenient—it can be dangerous.
When it comes to medical tests, one wrong report can lead to wrong prescriptions, which could worsen the situation. That’s why diagnostic centres play such a key role.
Reliable Diagnostics, a reputed diagnostic centre in South Kolkata, ensures you get an accurate diagnosis for timely care.
Here’s how to ensure you choose the right diagnostic centre for your health needs.
How to Verify the Credibility of a Diagnostic Centre?

You should always start by verifying the credibility of the centre, which goes beyond online reviews. A trustworthy diagnostic centre will have relevant accreditations that assure you of the quality of their services.
NABL Accreditation for Labs (Pathology)
When you search for a pathology lab, check if the lab holds NABL accreditation (National Accreditation Board for Testing and Calibration Laboratories). This accreditation ensures that the lab adheres to rigorous standards for testing, equipment calibration, and report accuracy.
What NABL means: NABL accreditation guarantees that the lab’s tests are reliable and performed by qualified professionals using up-to-date, quality-controlled equipment.
How can you verify a NABL-accredited lab?
- Visit the official NABL website.
- Search for the lab using the lab’s certificate number or name.
- Verify that the lab’s accreditation is active and up to date.
Reliable Diagnostics, a diagnostic centre in South Kolkata, holds NABL accreditation and ensures precise test reports.
NABH Standards for Imaging Centres (Radiology)
For MRI centres or CT scan centres, check if they are accredited by NABH (National Accreditation Board for Hospitals & Healthcare Providers). NABH certification ensures that imaging centres maintain high standards in equipment calibration, image quality, and patient safety.
Imaging quality is important—clear, precise scans can make a huge difference in accurate diagnosis.
Is the Centre Truly “One Roof” or Just Saying It?
A one-stop diagnostic centre should offer a wide variety of services. You shouldn’t have to visit multiple centres for different tests.
Pathology Coverage: From Routine to Specialised
Look for pathology coverage that includes routine tests like CBC, thyroid, diabetes, lipid profiles, and more specialised tests for hormones, vitamins, and cultures. A good diagnostic centre will cover a broad spectrum to avoid multiple visits.
Radiology Coverage: What Scans Are Available?
The best diagnostic centre should offer a variety of radiology tests like MRI, CT scans, X-rays, USG, Colour Doppler, and mammography. The more comprehensive the offering, the easier it is to get everything done in one visit.
What Determines Report Accuracy?

Report accuracy is determined by the entire process, from sample collection to final reporting. It’s not just about having the latest machines; it’s about having the right processes in place.
Sample Collection Standards (This is Where Good Labs Win)
For accurate blood tests, make sure the diagnostic centre employs trained phlebotomists who understand the proper collection procedures. Using the correct tubes, providing fasting guidelines, and ensuring proper sample labelling are vital for accurate results.
Internal Quality Checks + Qualified Oversight
Does the lab have qualified pathologists or radiologists reviewing the results? Many centres use automated systems, but oversight by qualified professionals adds another layer of assurance to the results. This review process is key to identifying any potential discrepancies in the findings.
Turnaround Time (TAT): How Fast Will You Get Your Results?
Turnaround time (TAT) is crucial, especially when you need quick results for treatment decisions.
What’s the Expected Report Time for Common Tests?
You need to ask the diagnostic centre about the expected turnaround time for common tests. Basic blood tests might be available the same day, but complex tests like MRI or CT scans could take up to 48 hours or more.
How Will You Receive Reports?
Make sure you confirm how the same-day diagnostic test report will be delivered. Today, many centres offer WhatsApp reports, email, or access to a patient portal. Additionally, check if they offer reprints in case you need them for other consultations.

Why is Hygiene & Safety Important for a Diagnostic Centre?
Good hygiene is an essential part of any diagnostic centre. Cleanliness ensures that the centre is operating safely and provides a comfortable environment for patients.
Clean Waiting Area + Sample Room Hygiene
A clean waiting area and sample collection rooms reflect the centre’s commitment to patient safety and comfort. Check if the waiting areas are spacious, clean, and well-maintained.
Radiology Safety Basics
When dealing with imaging services like MRI and CT scans, ensure that the centre follows radiology safety protocols. This helps minimise any risks involved in diagnostic imaging.
Price Transparency (Avoid Hidden Charges)
Transparent pricing helps you avoid surprises. Always ask for a detailed breakdown of the costs.
Rate Cards + What’s Included
Ensure that the diagnostic centre provides you with a clear rate card for all the services, including home collection charges, doctor consultation fees, and repeat report fees.
Health Packages: Useful or Just Marketing?
Health packages can be a good option for routine checkups, but avoid packages that make vague claims. Choose packages based on your age and health status, but don’t fall for exaggerated marketing promises.
How to Check Reviews When Choosing a Diagnostic Centre?
When checking reviews, focus on the specific aspects of service that are important for you.
What to Look for in Real Patient Feedback
Real reviews will mention on-time reports, proper fasting guidance, and clear billing. These are the things that matter when choosing a reliable diagnostic centre.
Red Flags
Be cautious if reviews mention needing to repeat tests, delayed reports, or hidden charges. These are serious red flags.
