Department of Laboratory Medicine

Overview

Laboratory Medicine has seen remarkable advancements in recent decades, with cutting-edge analytical techniques and technology accelerating progress. These innovations have led to breakthroughs in diagnostic procedures, enabling rapid and accurate diagnoses, aligning with our commitment to improving human lives through reliable diagnostic insights.

Our laboratory operates round-the-clock, providing 24-hour service to hospital patients and their physicians. Each section is overseen by qualified senior laboratory technologists and specialized biomedical scientists, ensuring access to the latest diagnostic pathology tools for patient diagnosis and treatment. With over 95% of tests conducted in-house, we ensure efficiency and precision in our diagnostic processes.

Led by Dr. Susheela J. Innah, an experienced pathologist specializing in Clinical Chemistry, Immunology, Endocrinology, Hematology, and Blood Banking, and managed by Sr. Gordian, an Operations and Quality Manager with over two decades of leadership experience, our laboratory team ensures comprehensive laboratory services and clinical consultation for patients at Jubilee Mission Medical College Hospital, available 24/7.

Sample Journey

For most people, lab test is all about giving a blood sample or urine sample and then coming back later for collecting the test report. But do you know what happens after the sample is given? Do you know what is going on behind the scenes inside the testing lab? Do you know how your test results are determined and reported? In this section, we try to provide you with a walk through of a blood sample from sample collection to completion and dispatch of reports.

Step 1 : Collection of the blood sample

A trained laboratory technician called “Phlebotomist” usually performs this. Alternatively a doctor or a trained nurse could also do this. In many cases, blood is drawn from the vein located near the outer portion of the arm near the elbow. Phlebotomists are trained to efficiently handle this process which appears simple, yet requires considerable skill and care. If done correctly, the needle poke is usually painless.

Step 2 : Labeling the blood sample

The next step is to correctly label the sample. In our Lab, bar-coded labels are used which are affixed on the tube. The bar code incorporates patient name, specimen identification number and the lab-id allotted for that patient test Computer generated bar code data saves time and reduces potential labeling errors. It also helps improve tracking efficiencies from sample processing stage to the report generation stage.

Step 3 : Documenting the specimen

Blood sample is handed it over to respective departments. With the barcode label, the data is validated so that the tests that are run match with the person whose specimens have been collected

Step 4 : Running the Tests

Tests are today performed by sophisticated machines and not by humans holding pipettes in their mouth! Large labs have machines that can run high volume of sample batches. Blood samples are analysed (depending on the tests) in a machine called Blood Analyser. These are also called as Auto Analysers. Depending on the nature of the tests, different machines are used for analysing the sample. During the testing process, chemical reagents are used on the sample, depending on what test is being performed. Different machines are used for performing different types of tests on different types of sample

Step 5 : Getting the results

Most of the automated blood analysers used today, automatically generate the results in electronic format, and many of them are interfaced to the computer.

When samples are processed in multiple analysers and equipments, the results are verified and validated as part of the internal quality control process. After verification they are consolidated and the results are fed into the Lab Information system (LIS). From here the reports gets printed and usually get signed off by the Senior pathologist, who performs one more round of scrutiny before sign off. Sometimes if the figures look too abnormal, which pre-empts some serious investigation, the lab would call the referring doctor directly and discuss the issue. For some tests, results are available within hours, for some by the end of the day. Some tests could take 48-72 hours to get the results. Some tests could take much longer. It depends upon the complexity of the test, processing frequency in the lab and other factors.

Step 6 : Documenting the specimen

Blood sample is handed it over to respective departments. With the barcode label, the data is validated so that the tests that are run match with the person whose specimens have been collected
