A leaky transport container is considered what overall specimen outcome?

Rejection

A sputum Gram stain with fewer than how many WBC per LPF may lead to rejection?

25 WBC

A sputum Gram stain with more than how many epithelial cells per LPF may lead to rejection?

10 EC

A sputum direct Gram stain with fewer than 25 WBC and more than 10 epithelial cells per LPF is a reason for specimen rejection

True

An inadequate specimen is a reason for specimen rejection

True

An inappropriate or leaky transport container is a reason for specimen rejection

True

An incomplete requisition is a reason for specimen rejection

True

Anaerobic culture from a site where anaerobes are indigenous is a reason for specimen rejection

True

Mismatch between requisition and specimen label leads to what overall specimen outcome?

Rejection

Mismatched information between label and requisition is a reason for specimen rejection

True

Multiple same-source specimens on the same day may lead to what overall specimen outcome?

Rejection

Multiple specimens from the same source on the same day is a reason for specimen rejection
