Things You Need To Know Before Requesting Laboratory Tests

A) Specimen collection

1. The specimen collection instructions described in this website must be strictly followed.Please contact the laboratory before specimen collection should you have any query.

2. Please contact the laboratory for specimen containers. They are provided as a part of the services.

B) Specimen labeling

1. It is a must for all specimens and the corresponding Laboratory Investigation Request Forms to be labeled with DOUBLE IDENTITIES. It is recommended the HKID Number (or a unique Clinic Number generated by the clinic) and the patient’s name be used as the identities.

2. A Form Number printed on detachable labels of the Laboratory Investigation Request Form can also be used as one of the identities if HKID Number and unique Clinic Number are not available. Please also mark the Form Number in your patient’s record when it is used.

Please note that a cumulative report will only be generated when the HKID Number or unique Clinic Number is provided although the Form Number can be used as a patient’s identity.

C) Filling in the Laboratory Investigation Request Form

A Laboratory Investigation Request form (LIRF) must be submitted with all laboratory tests request. The following information should be provided in the Form:

1. Patient’s name

2. Patient’s sex and age (preferably with date of birth)

3. Patient’s HKID Number or an unique Clinic Number (Form Number if both are absent)

4. Date and time when the specimen(s) is (are) taken

5. Brief clinical history of patient

6. Fasting or random sample

7. Time and dosage of last dose for drug toxicology

8. Tests requested

9. Clinic address and requesting clinician’s signature or name stamp

10. Payment method either by cash or on account

D) Specimen pick-up

A) The laboratory provides free specimen pick-up service. Please telephone us immediately once the specimen is available. For locations along MTR, we guarantee all specimens arrive at the laboratory within 3 hours after receiving your call.

B) We recommend keeping the specimens at temperature below 25°C before pick-up. Please be reminded NEVER put any specimen in refrigerators below 4°C. For details, please refer to instruction for individual test.

E) Acceptance and rejection criteria

Usually, all the relevant information listed in (C) above should be provided for a sample that is regarded as acceptable. However, the laboratory requests meet the minimal acceptance criteria as follows are still acceptable provided that the missing information have been provided and confirmed by our staff:

1. Request form without name or HKID but is individually packed with the specimen so that it is identifiable.

2. Lacking of patient’s particulars on the LIRF (e.g. sex, age/date of birth)

3. Requested test is not specified.

4. Due to the difficulties in re-collecting specimens, specimens of insufficient quantity, but dilution is possible, will be individually considered.

Laboratory requests will be rejected as follows:

1. The patient ’s identity is in doubt.

2. The specimen is unlabelled.

3. The client cannot confidently identify the specimen’s identity.

4. The specimen is insufficient and not possible to dilute.

5. Wrong type of specimen is taken, e.g. EDTA sample for potassium measurement.

6. The specimen and the corresponding LIRF cannot be matched accurately.

F) Limitations and interferences of laboratory tests

1. Lipaemia of blood sample may interfere with laboratory tests. It is not recommended to collect blood sample from a patient shortly after a heavy meal even if the requested test does not require a fasting sample.

2. Haemolysis of sample will give erroneous elevated or lowered laboratory test results. Avoid delivering blood sample into containers without removing the needle from the syringe.

3. Prolonged storage of sample will affect laboratory results. Call us as soon as the sample has been collected.

4. Modern laboratories apply immunoassays for most of the tumour markers and hormones tests. It is known that heterophilic antibodies in human serum can react with reagent immunoglobulins, interfering with in vitro immunoassays. Patients routinely exposed to animals or animal serum products can be prone to this interference and anomalous values may be observed. Diagnosis should always be made in conjunction with clinical evaluations.

G) Re-submission of sample for repeat testing or confirmation

The laboratory charges will be waived for repeat testing or confirmation under the conditions as follows:

1. Sample haemolysis

2. Sample lipaemia

3. Confirmation for the tests not able to provide final results with the first sample.

H) Reference intervals

Reference intervals will be provided in the report for most of the laboratory tests with quantitative results.

I) Policy on protection and disclosure of personal information

1. All medical laboratory technologists in our laboratory are registered under the Hong Kong Medical Laboratory Technologist Board.
