==Most useful local documents==
If you're on-call, know where to find local policies, manuals and procedures that are relevant to the departments you may receive calls from. The following local documents are generally most important:
*'''Blood bank''': 
:*Cutoff values for '''blood product transfusions'''. {{further|Blood bank}}
:*The [https://www.cdc.gov/nhsn/pdfs/biovigilance/bv-hv-protocol-current.pdf NHSN Biovigilance] document on evaluating suspected '''transfusion reactions'''.
*'''Chemistry'''
:*'''Package inserts''' for instruments used in the laboratory
:*Cutoffs for classifying various test results as '''critical''', and how you are going to proceed in such cases.
Also keep an updated '''telephone list''', including the supervisors for relevant departments.

Topics with individual articles:
*[[Blood bank]]
:*[[Irradiated blood]]

;Incompatible plasma
In emergencies, it is acceptable to approve plasma that is ABO incompatible or possibly incompatible (such as from a type A donor to a recipient with unknown blood type).

*[[Suspected blasts on peripheral blood smear]]

==Suspected falsely low TSH==
If a clinician thinks a TSH result is falsely low (generally signs of hypothyroidism but TSH is not elevated), first check with the lab if their TSH assay is susceptible to high patient biotin levels, and if it is, ask the clinician if the patient takes biotin supplementation, which can explain the low TSH levels.
