The laboratory provides clinical laboratory and diagnostic services for routine health investigations, specialized testing and diagnostic assessment. Established in 1987, the organization has developed a network of diagnostic facilities and collection centres, with its main facility located in North Nazimabad, Karachi. The laboratory operates around the clock and provides diagnostic services through its network of branches.
The diagnostic network has multiple locations in Karachi and has expanded its services to other cities in Pakistan. Different branches provide laboratory testing and selected diagnostic services according to their facilities. Branch-level availability can vary, so patients should confirm the required service before visiting.
Clinical pathology covers laboratory examination of blood, serum, plasma, urine and other clinical specimens. The laboratory also performs analysis of samples received from hospitals, collection units and research-related facilities. Internal and external quality-control procedures are part of its laboratory operations.
The hematology department provides investigations related to blood cells, blood-forming organs and hematological conditions. Routine and specialized hematology investigations may be performed, with complete blood-count and microscopy-related evaluation forming part of the laboratory's diagnostic services.
Clinical chemistry services involve analysis of blood, serum and plasma for different biochemical parameters. Testing may cover routine chemistry, metabolic investigations, organ-function parameters and other specialized biochemical investigations according to the available test menu.
Hormonal investigations are included among the laboratory's diagnostic capabilities. Testing can involve different hormone parameters and endocrine-related investigations based on the physician's request and the laboratory's current test menu.
Microbiology investigations are available for appropriate clinical specimens. Depending on the requested test, services may include microscopic examination, culture and other laboratory methods used for investigating microorganisms.
Histopathology involves laboratory examination of tissue specimens. Tissue samples can be processed and examined microscopically to provide diagnostic information for physicians.
The laboratory provides specialized diagnostic investigations in addition to routine laboratory testing. Molecular and other advanced tests may be available depending on the specimen, clinical requirement and current laboratory test menu.
Quality assurance is an important part of laboratory operations. The laboratory's published department information describes internal and external quality control and assurance procedures, as well as data handling and testing processes.
Selected diagnostic centres also provide imaging and diagnostic procedures. Publicly listed services include digital X-ray, ultrasound, colour Doppler, MRI, CT scan, DEXA scan and echocardiography. Availability depends on the individual branch.
Home sample collection is available through the network. The official website states that online-booked tests are eligible for free home sample collection, with a trained phlebotomist arranged from the nearest branch after booking confirmation. Collection timing can depend on location, weather and other local conditions.
Patients can book laboratory tests online and use digital services for accessing diagnostic information. The laboratory also provides a mobile application with features including branch location, directions and nearest-branch search.
Report processing time depends on the type of investigation. Routine laboratory tests may have different turnaround times from specialized or advanced investigations. Patients can confirm the expected reporting time when booking a specific test.
The official website states that the laboratory operates 24 hours a day. Individual branches may have different service arrangements, particularly for imaging, sample collection and specialized investigations.
The main published contact details include the North Nazimabad facility at SC-13, Block H, North Nazimabad Town, Karachi, with the central UAN +92 (021) 111 786 986 and email info@essalab.com.
Test availability, charges, sample requirements, preparation instructions and report turnaround time can vary between investigations and branches. Patients should confirm the specific test and collection requirements before visiting or booking home sample collection.
A wide range of blood investigations is available for routine screening, monitoring and specialized diagnostic requirements. The exact test selection depends on the laboratory's current test menu and the patient's clinical requirements.
Complete Blood Count (CBC) evaluates major blood-cell parameters, including hemoglobin, red blood cells, white blood cells and platelets. It is commonly requested as part of routine hematology investigations.
Blood glucose investigations are available for assessment and monitoring of blood sugar levels. Depending on the requested investigation, testing may include different glucose measurements and diabetes-related laboratory parameters.
Liver-related biochemical investigations may include measurements such as bilirubin, liver enzymes and other related parameters. The appropriate combination of tests depends on the physician's request.
Kidney-related testing may include creatinine, urea and other biochemical parameters used to assess renal function and related metabolic changes.
Lipid investigations can include total cholesterol, HDL cholesterol, LDL cholesterol and triglycerides. Individual lipid tests or a complete lipid profile may be requested.
Thyroid and other hormonal investigations are available as part of the laboratory's specialized testing services. The exact hormones tested depend on the requested investigation and current laboratory availability.
Selected vitamin and nutritional investigations may be available for evaluating vitamin levels and related nutritional parameters. Patients should confirm the specific vitamin test before sample collection.
Hematology services cover routine and specialized blood investigations. The department also performs microscopy-related evaluation and provides diagnostic testing for a range of hematological conditions.
Immunology and serology testing can include antigen- and antibody-based investigations. These tests may be used for selected infectious, immune-related and other clinical investigations.
Microbiology services can include examination and culture of suitable specimens. Depending on the requested test, samples may include urine, blood, sputum, swabs or other clinical specimens.
Histopathology involves examination of tissue specimens under laboratory conditions. Tissue processing and microscopic assessment can provide diagnostic findings for physicians.
Specialized laboratory testing may include advanced molecular investigations and other tests that require specific laboratory methods. Availability depends on the current test menu and specimen requirements.
Urine and other biological specimens can be tested for different laboratory investigations. The required specimen type and collection procedure depend on the specific test.
Selected branches provide diagnostic imaging services including digital X-ray, ultrasound, colour Doppler, MRI, CT scan and DEXA scan. Echocardiography and other diagnostic procedures are also listed among available services at selected locations.
Home collection is available for eligible laboratory tests. Online bookings can be followed by confirmation from the laboratory team, after which a phlebotomist may be arranged for sample collection from the patient's location.
Patients can book selected tests online through the laboratory's digital platform. The website states that representatives contact customers after an online booking to confirm the booking and address details.
Turnaround time depends on the investigation. Routine tests may be processed differently from specialized hematology, molecular, histopathology and other advanced laboratory investigations.
Not every test or imaging service is necessarily available at every branch. Before visiting, patients should confirm the test name, sample requirements, preparation or fasting instructions, charges, collection location and expected report time.
