I came across a very valuable paper in Clinica Chimica Acta on the stability of hematology controls for MCV. (Some of you are already guessing what this is going to be about...)

If you take a hematology control, how many SDs should you expect to see it shift at week 5 of use versus the first week of use? In other words, what is the SDI you should expect?

• 1 SDI
• 2 SDI
• 3 SDI
• 4 SDI
• 5 SDI
• higher than 5 SDI

The answer, after the jump...

• analytical processes
• post-analytical processes

A recent news investigation produced a litany of laboratory errors. Can you guess which of these lab errors actually happened?

• a blood screening test fails to identify a critical blood disorder in a pregnant woman. Her child dies 3 weeks after being born
• an HIV test falsely identifies a husband as HIV positive. The couple separates, the wife unwilling to trust the husband anymore.
• a paternity test sample gets switched: a father is falsely told that his daughter is not his biological child. The family splits up. Nearly 4 years later, the laboratory contacts him and tells him he was the father. The father-daughter bond remains broken.

The answer, after the jump.

As some of you know, this year's new "Westgard Wear" novelty was not a piece of clothing, nor a Bobblehead, but instead an 8GB USB thumb drive:

But if you look at this picture of two of the thumb drives, is there anything that jumps out at you?
