Safety & ComplianceCâu 46 / 100

a.That the specimen was collected while the donor was fasting
b.Every person who handled the specimen and every transfer from collection to reporting
c.That the correct tube additive was used
d.That the laboratory participates in proficiency testing
Giải thích
Chain of custody is a legal record documenting identity, handling and transfer of a specimen at every step so its integrity can be defended in court. It typically includes a tamper-evident seal, dated signatures at each transfer and secure storage. Fasting status, additive selection and proficiency testing are quality issues but are not what a chain of custody form proves.
