Every morning in the lab was the same, collection and careful labelling of hundreds of tubes of blood, using different containers, some with preservative chemicals ready added, Fluoride for the glucose and alcohol specimens, Heparin when we wanted to get plasma, and plain tubes when we wanted to allow the blood to clot to produce serum. Then we centrifuged the tubes and separated the aqueous component from the cellular into a different tube, again clearly labelled. It took an hour or two every morning, and it had to be careful meticulous work. A wrong label could be fatal, if the wrong blood analysis result was applied to the medical treatment of a patient, so we were trained and certified and legally responsible for our own work.
It was also dangerous. The second year I was working in the lab, there was an outbreak of Hepatitis C in a lab. in Edinburgh, 11 technicians were hospitalised, and 2 died.
We started wearing gloves when handling blood after that, and masks 2 years later after other outbreaks.
We were terribly casual in our attitudes to safety in the 70s. In our lab we also ran tests for hormones found in pregnancies. This was a test on urine, and used a combination of reagents and solvents that would make a health and safety analyst run away screaming.

I'm a bit apprehensive about going back to NLHS after the test, I hope everything will run smoothly, but you never know.
And then I've got to print out the final version of the reports for the DPs to peruse over the weekend.
What fun!

ReplyDeleteIt'll run as smoothly as SSR*, when, to quote our previous principal, "The whole school will fall silent."
Good luck with the test, my friend.

Fascinating. That explains why those P houses are so dangerous too?
