Clinical BiochemistryHematology and Pathology

Microbiology and Serology

The Laboratory services at Dr. Mohan’s Diabetes Specialities Centre is unique in using advanced technology and having fully automated walk away systems in the department of Biochemistry, Hematology, Pathology, Microbiology and Serology which provide round the clock services, seven days a week. The laboratory is equipped with state-of-the-art equipment and has a team of efficient, motivated, knowledgeable and qualified biochemists and technical staff who are constantly involved in producing accurate and reliable results and upholding quality assurance.

All the blood samples in the laboratory testing are collected using vacutainer system of collection and labeled with bi-directional barcodes which avoids cross contamination and pre analytical error. Bi-directional barcoded samples are directly fed into the respective analyzer and results are automatically transmitted to Laboratory Information System (LIS) without manual entry to avoid analytical and post analytical error.

The laboratory has been accredited by the following National and International organizations,

  • COLLEGE OF AMERICAN PATHOLOGISTS (CAP), USA (The second such lab in Chennai)
  • World’s First ISO 9001:2008 Certified Diabetes laboratory,

The laboratory’s Quality Monitoring system helps to improve the accuracy and reliability of results in term of internal Quality Control (QC) as well as external proficiency testing materials. Internal QC material is analyzed at predetermined intervals along with patient samples to monitor systemic and random errors. These materials are traceable to international certified reference material so that accuracy of measurements is monitored periodically.

Our laboratory’s quality is assured by the International and National EXTERNAL QUALITY ASSURANCE (EQA) programme conducted by

  • College of American Pathologists (CAP), Illinois, USA
  • Bio-Rad Laboratories, California, USA
  • Christian Medical College (CMC), Vellore, India
  • All India Institute of Medical Sciences (AIIMS), New Delhi, India
  • Amala Institute of Medical Sciences (AIMS), Thrissur, India

Department of Clinical Biochemistry

The initial step towards a cure is the diagnosis. The faster and more accurate the diagnosis, the easier and better the cure. The biochemistry department goes the extra mile by being committed to ensuring accuracy and precision in specimen handling, clinical testing and making available the latest investigation in the field, so as to facilitate faster diagnosis

The Biochemistry Department performs more than 3000 tests per day pertaining to 48 parameters. All the biochemistry assays are performed in high throughput analyzers,

  • Beckman Coulter AU2700 & AU480 chemistry analyzer (throughput 2100 tests/hr)
  • Roche Cobas e601 Immunoassay module for selective sample processing of immunological parameters with the ECL technology. (throughput 170 tests/hr)
  • India’s first Bio-Rad Variant II turbo Glycated Hemoglobin (HbA1c) analyzer (throughput 40 test/hr), which has been certified by the National Glycohaemoglobin Standardization Program (NGSP), USA.
  • SEBIA CAPILLARYS 2 Flex Piercing System, a fully automated solution for high quality HbA1c testing (throughput 36 test/hr)
  • EasyLyte Na/K & Cl analyzers, a completely automated, microprocessor controlled electrolyte system which used to analyse sodium, potassium, and chloride in whole blood, serum, plasma, or urine.
  • Bio-Rad iMark™ microplate ELISA reader for the analysis of Anti-GAD, Anti-IA2, Tissue transglutaminase antibody (TTG), Zinc Transporter 8 antibody etc

Department of Hematology

The Hematology Department provides laboratory services for the diagnosis and treatment of all blood related disorders such as anemia, bleeding disorders and malignant conditions related to blood cells such as leukemia, lymphoma and myeloma. Complete Blood Counts (CBC) are analysed by Sysmex XT1800i (80 samples/hour) analyzer and Coagulation tests are performed in the automated Random Access Coagulation analyzer Sysmex CA 50.

Department of Clinical Pathology

Urine analysis is used in detecting a variety of renal, pre-renal, urinary tract diseases. A semi-automated Cobas u 411 (600 test strips/hour) is used to rapidly detect PH, specific gravity, protein, glucose, bilirubin and other compounds in urine. The technician examines urine for microscopic elements such as red blood cells, pus cells, epithelial cells, casts and crystals.

Department of Microbiology and Serology

The Microbiology and Serology Department has high-end facilities for processing and reporting patient’s specimens in the field of diagnostic bacteriology, virology and parasites, which may cause a range of diseases.

In addition to identification, the department is actively involved in infection control activities of the hospital.

60 Minutes Reports

The samples are processed immediately; the reports are validated continuously and released. The turnaround time after postprandial sample reaches the lab, is on an average 60 minutes. The results are available within this period which reduces waiting time of patients.
