Tests in this list are reported within 3 hours of sample collection, 24×7×365. For most of them you can walk in at any hour without calling first. Tests that need fasting, timed samples or a 24-hour urine collection still need that preparation first, so they are grouped separately at the end of this list: call 93111 93111 before you come.

No additional urgent or night-time charge.Urgent processing and night-time service do not attract a separate surcharge.

When waiting until tomorrow is not practical

When might you need an urgent test?

The need may be medical—or simply time-critical. These are common situations in which access to testing and reporting beyond normal working hours matters.

Your doctor wants a test or repeat test urgently

A treating doctor may want a parameter checked or repeated within hours rather than waiting for the next morning.

Investigation during an acute illness

You have been medically evaluated and laboratory investigations have been requested the same day or night.

An abnormal result needs rechecking

Your doctor has asked for a laboratory value to be repeated within a short interval for clinical follow-up.

Procedure or surgery the next morning

A required laboratory investigation is still pending before a planned early-morning procedure, surgery or admission.

A time-sensitive specimen should start processing

Some specimens, including microbiology samples, benefit from entering the laboratory workflow promptly even though the final result may take longer.

Tomorrow’s consultation or hospital visit needs the report

You discover late in the day that the doctor expects an investigation before an early appointment or admission.

A test was missed or recollection is required

One investigation was omitted, or an unsuitable earlier specimen needs recollection before the next appointment.

A time-bound travel or documentation requirement

A laboratory report is needed for travel, fitness, insurance or another institutional deadline and normal working hours are not enough.

For a medical emergency requiring immediate treatment, go to an appropriate hospital emergency department. A pathology laboratory provides diagnostic testing and does not replace emergency medical care.

2 AM should not mean a different standard

Who reports your result at night?

The clock changes. Our reporting responsibility does not.

The laboratory remains operational rather than functioning only as a sample collection point.

Relevant testing continues overnight across multiple laboratory disciplines.

Every report issued, including at night, is medically reported by qualified laboratory doctors.

Urgent reporting does not carry an extra surcharge simply because it is urgent or after hours.

Medical report review workflow at Dr Bhasin's Lab

Medical reporting continues at night. The patient should not interpret this as an in-person doctor consultation service at midnight.

Inside the night shift

Which tests run overnight?

The exact test menu varies by investigation, but multiple core laboratory disciplines remain operational overnight.

Biochemistry

Routine chemistry and many urgent chemistry investigations continue overnight.

Haematology

Eligible haematology and coagulation investigations can be processed during the night.

Clinical Pathology

Eligible urine, fluid and related pathology testing can enter the overnight workflow.

Serology

Selected serological investigations continue based on the test and laboratory workflow.

Selected Molecular Tests

Some molecular investigations are available overnight; test-specific availability should be confirmed.

Microbiology Processing

Appropriate processing and incubation for eligible culture specimens can begin during the night.

An important distinction

Do cultures start at night?

A culture sample submitted at night may still require 48 hours or longer for its final result, depending on the specimen and organism. However, appropriate initial processing and incubation can begin during the night instead of simply waiting for the next working day.

This is why a genuinely operational night laboratory can matter even when the final test result is not a “3-hour report”.

Transparent availability

Is every test available at every hour?

No. The laboratory is open 24×7, but certain procedure-dependent or specially scheduled services are not collected throughout the night.

Semen analysis is not a night-time walk-in service.
FNAC requires scheduling and is not collected throughout the night.
For specialised tests, call the 24×7 team to confirm collection requirements and reporting time.

Are reports issued at night medically reported by a doctor?

No. The physical laboratory and call centre operate 24×7. Home collection runs from 6 AM to midnight across Delhi and NCR, while hospital sample logistics continue through the night.

Are culture reports available in 3 hours?

No. Cultures require their normal biological incubation and reporting time. However, appropriate processing and incubation of eligible culture samples can begin during the night rather than waiting for the following morning.

Is every pathology test available as a night walk-in?

No. Certain services such as semen analysis and FNAC are not collected as unrestricted night-time walk-ins, and some specialised tests require availability confirmation. Call the 24×7 team for test-specific guidance.

Need a test urgently?

Day or night, you do not have to wait for normal laboratory hours.

Walk into Greater Kailash-I, search the urgent test menu, or call the 24×7 laboratory team.
