Most useful local documents
Practices and cutoff values differ between laboratories, so if you are going to be on call, the following local documents are generally most important to keep so that you can quickly look it up when needed:
- Cutoff values for blood product transfusions. Further information: Blood bank
- Cutoffs for classifying various test results as critical, and how you are going to proceed in such cases.
Topics with individual articles:
- 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).
Other topics with individual articles
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.
