Ideally, the microbiological samples should be collected before beginning any treatment with exceptions in seriously diseased conditions. The microflora gets altered on the administration of antibiotics which can lead to potentially misleading culture results.

The MLT should make sure that all containers for sample collection are sterile with close-fitting lids. These should be packed along with the laboratory test request form, TRF, in a sealed packet with separate divisions for the sample and the TRF.
Hands should be washed before and after sample collection and appropriate personal protective equipment should be worn while collecting or handling the specimen.
A fully prepared first aid box should be available before any procedure is carried out.
Informed written consent in case of diseases like HIV should be taken. A TRF which is duly filled and stamped by the treating clinician and readiness of the patient to get it done is considered as implied consent to perform the test. A standard patient consent form with the signature of the patient is also collected before any sample collection.

Post-procedural care should be taken too by the technician.
A pressure bandage has no adhesive and is used to control bleeding and encourage clotting without constricting normal blood circulation.
In case of needlestick injury or any other skin puncture or wound, the wound should be washed and some bleeding should be encouraged.
2. Data security
Only laboratory staff specifically assigned for this purpose should be able to access the data and a routine backup should be taken.
3. Microbiology laboratory results that are reported should be accurate, significant, and clinically relevant and specimens of poor quality must be rejected.
Getting the right diagnosis is thus contingent upon laboratory results that are accurate and clinically relevant. Confirming the provisional diagnosis of the clinician, ruling out a diagnosis, detecting disease, and regulating therapy are dependent on the tests performed by the medical laboratory technicians.
In recent times, the increased demand of DMLT holders for laboratory tests and their sensitivity and specificity has led to the introduction of more specialized and sophisticated procedures including automation and computerization. The medical laboratory science practitioner of today must, of necessity, be theoretically sound and practically effective in his/her discipline.
