· REQUEST FORM INFORMATION
The laboratory uses standard request forms to control the ordering of common laboratory requests. The laboratory accepts/receives two types of request forms in our laboratory.
a) Fomema Medical Examination Form
Pre-printed from Fomema with foreign worker and clinician identification, the clinician provides date of sample collection. Clinic shall check and ensure the clinic name and laboratory name on Fomema Medical Examination Form are correct before proceeding to draw the foreign worker’s blood.
b) Pathology Request Form (for commercial sample) The essential information on the request form are:
· Patient’s full name
· Patient’s IC or Passport number
· Patient’s date of birth
· Patient’s worker code
· Patient’s gender
· Date and time of specimen collection
· Type of specimen collected and if appropriate. E.g: The anatomical site of origin or tick the relevant box
· Specimen nature
· Report Urgency
· Name of the clinician
· Location to where the results should be reported
· Test requested
· Clinical history, clinical advice and diagnosis if needed.
No fasting is required. For female, ensure patient is not menstruating before collection of the urine sample.
For optimal results, the patient should be on a stable diet for 2-3 weeks prior to testing. Patient should fast for 12 to 14 hours before blood collection. Fasting includes no food or drink except for plain water.
Glucose Tolerance Test GTT (Non-Pregnant)
Patient should be fasting for 12 to 14 hours (no food or drink, except for water). A blood specimen will be drawn after which the patient will be given a special drink. Patient’s blood will be drawn once each hour after the patient has finished the drink. The number of blood draws may vary and patient may be required for blood draws from 2 to 6 hours. Patient’s doctor will decide how many hours blood draws will be required per patient. Sufficient time should be allowed for GTT to be completed. Patient will need to allow approximately one hour more than the number of hours patient’s physician requested. For example, if patient’s physician ordered a 2 hour glucose tolerance, then three (3) hours should be allowed for the GTT to be completed.
Cortisol may be tested in blood or urine.
If blood cortisol levels are requested by patient’s physician, patients may be asked to have blood drawn once (random cortisol) or multiple times. Patient’s physician will inform patient if patient is required to have multiple blood draws for patient’s cortisol testing. Cortisol blood tests may be drawn at about 8 am, when cortisol should be at its peak, and again at about 4pm, when the level should have dropped.
If patient’s physician requests urine cortisol, patient will be asked to collect either a 24- hour urine or a single first morning specimen. Patient’s physician will inform patient of the type of urine collection patient will need.
Vitamin B12 and Folate
A fasting specimen (no food or drink, except for water) for 12- 14 hours before blood is drawn is preferred. However, patient’s physician may request that patient have patient’s blood drawn when patient is not fasting.
