week 16...!!!!

Well..... For the past 2 weeks i was attached to the Specimen Reception (SR)department. It is the pre-analytical part of the whole laboratory, where the specimens are received and labelled.

It is here, in this department where I found out that mistakes are simply not tolerated. The personnels must be constantly on their toes, fast and at the same time, do their work accurately. A simple mistake of not tallying up the names on the specimens to the name on the form, can spell disaster.

There's no tests involved, but I am to include the workflow of the SR department.


  • The dispatch crew will arrive with the samples from the various clinics. The samples are received by the personnels there, where the number of samples and specimens are counted and tallied with those counted by the dispatch crew.

  • The samples are then passed over to another group of personnels who will open the samples. Here, they will check that the names on the specimens tally with those in the request form, and write down the number and type of specimens that they receive for that request form only.

For example: 2 long plain tubes, 1 EDTA tube and 1 urine will be written as 'LP x 2, E, U' in a vertical fashion.

Then, they would sign their initials before seprating the samples into single profile (includes only HIV, VDRL and tests for malaria parasites) and profile (which is all the other tests other than those previously named).

  • The seperated samples are then subjected to primary barcoding, where the request forms and specimens are labelled with their own individual barcode, and allocated into baskets according to the tests that are requested (such as HIV samples are placed into the HIV basket, and so forth). Plain tubes, fluoride tubes, and certain EDTA tubes and urine (which are already poured into 5ml test tubes) are centrifuged. The rest are collected by the respective departments, such as Microbiology collecting the urine, stool and swab samples.

  • The centrifuged samples then goes through secondary barcoding, where certain specimens' serum are required to be aliquoted out due to the type of tests involved. The specimens are then loaded onto a sample tray, where they will be placed in the Sample Manager (explained in my earlier posts). The sample manager will then sort the specimens according to the type of tests to be run, and send them to the various machines via the transportation track.

  • At the end of the day, the specimens will undergo allocation and be placed in the cold room, where the will be kept for a week to 10days. This is so that if there is any additional tests that is to be run, we can still use the specimen and not bother the patient to go for another blood-taking session.

hey maya! what are the requirements for rejecting the specimens received? because for mine, one of the events in which a specimen will be rejected is when any of the forms sent to us are printed on used papers, the specimen will immediately be rejected. is it the same for you?

thanks

hey maya,

if its a HIV test that are requested, do they send an additional tube for it?
Because here at my lab, they have to send additional tube for HIV test. HIV test cannot share tubes with other test.

Hi Maya,

If mistakes are made, how will personnel be dealt with? Humans are bound to make mistakes, right?

How will personnel be trained to be fit for the specimen reception area?

Thankz!

hey athirah

hmmm...not the same at all. they're kinda budget, so re-use of paper is actually encouraged. haha

the specimens are rejected if:
-the specimens (such as stool) are not collected in sterile containers
-there's inadequate amount (includes blood or urine,either from collection or spillage)
-the names on the form and specimen does not tally
-the specimens are not labelled with the details of the patient

yeap. think that's it =)

olla sutiana!

hmmmm.... it depends really. usually they either collect blood in the big plain tube, or they give an additional one. in my lab, the sharing of tubes for HIV n other tests are accceptable, as long as there is enough serum/blood for the tests required.

wow han yang. dont yew ever run out of questions to ask??

my lab recently have adopted a 'point' system. the personnel who made a mistake, will be talked through, and be given demerit points. accumulation of such points will result in warning letters and eventually, not being able to get bonuses i think.

training wise, its like any other jobs. they will teach yew little by little. yew dont have to be 'fit' for anythg, as long as yew got common sense n a sense of getting the job done. yew'll do the easy jobs first, before proceeding to the more 'vital' jobs. like human makes mistakes, they can learn too.
