"The laboratory is committed towards effective quality management system by establishing quality objectives and ensuring continual improvement to comply with internal and customer requirements, national legislations and accreditation standards through clear communication and understanding among personnel"

We established a quality management system in the laboratory to assure quality in our testing and result reporting.

 

Accreditation

We are an ISO15189:2012 accredited laboratory since 2017.

 

External Quality Assurance Program

As part of our quality control program, we participate in external quality assurance or proficiency testing using the following programs:

  2. Royal College Pathology Australia (RCPA)


SPECIMEN COLLECTION PROCEDURE


COLLECTION OF SPECIMEN

The person collecting the blood sample is responsible for transcribing the following info on sample container:

·  Patient's name

·  Patient's MRN/PRN                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                      

·  Patient's identity card number (IC No.)

·  Date and year of birth

·  Sex of patient

·  Computer assigned lab # (if ordered through Vesalius)

 

  • Label tubes in the presence of the patient and right after the collection of the samples. Do not practice pre-labeling of the sample containers or tubes.

All specimens must be in properly sterile closed/capped container to avoid leakage.

For any special requests / send out the test, or if in doubt for what container to use, please contact or phone the laboratory to confirm type of blood container, blood volume, preservative and transport requirements. Microtainer systems are not ideal for send out test, it is available for pediatric and neonatal patient only.

Failure to properly label the tubes will require the specimens to be redrawn or recollection.

 

TRANSPORTATION OF SPECIMEN

  1. All specimens MUST be placed in a sealed biohazard bag(s). Separate different sample types in a different biohazard bag.

Special requirement for transport can be found in the test catalog for an individual test (e.g. specimen requires chilling for Ammonia test).

  • All specimen transported to the laboratory by hand must be carried in a specimen box/container.
  • All specimen transported to the laboratory by pneumatic tube must be wrapped with bubble wrap or any suitable cushioning inside the carrier capsule.

 

REJECTION OF SPECIMEN

JPMC laboratory will inform the respective wards or clinics to request for a redraw for the following:

·     Mislabeled and Unlabeled specimens

·     Insufficient amount for the test requested

·     Haemolysed specimens

·     Inappropriate specimen container or transport media

·     Anticoagulated specimens containing a blood clot

·     Improper storage or transport requirement

·     Discrepancies between requisition form and labeled tube

·     Specimen collected at the wrong time (e.g. drug level)

·     Specimen contamination or evidence of leakage
