Excellent questions and timing Dr. Kosfeld, and I hope the SA community will respond. This semester, I am teaching a course called Clinical Microscopy, which covers all the body fluids that require microscopy/cellular counts, and this week I have the lab called "special chemistries." I use the lab to teach the Watson- Schwartz test, SSA for proteins by gradation (1+, 2+, eg.), turbidimetry with spectrophotometry, and the Kingsbury Clark, to be comprehensive. I would love to know the answer to your questions because my students could use the time doing another urine microscopic before moving on to the next body fluid; if they are historical.
Your last question is the most relevant to me, "Does the ASCP certification exam still ask about them?" That answer will determine what I do in the future, and this week if others respond in time.
Thanks for the post.
Hi Kathy, Thank you for this timely feedback. I wanted to reply after reading the article that you referenced but am not able to bring it up at this time. However, I appreciate the advice; so, rather than completing a lab with antiquated testing I think I will discuss them and move on to the more needful microscopic examinations. I think some of my problem with moving on is a certain enjoyment in extracting recipes from old Tietz books to make the required reagents and the testing. I will continue to look for the article to search for other needs for updating labs and lectures that I may have overlooked. Thank you for the reference and feedback. Gerald
As a chemistry tech most of the urinalysis isn't my purview since Heme handles that in our labs, but I would definitely still do the SSA or at least emphasize it when discussing semi-quantitative urine protein because turbidimetric urine total protein assays are still what we use for many quantitative urine total protein methodologies. Be it SSA or benzethonium chloride it is a similar mechanism and it never hurts to reinforce methods they will learn elsewhere.
In the case of our labs it also serves to demonstrate the interconnectedness of all the disciplines.
Thank you, Stacey,
Although I work with the guidelines you sent to me, your response helps me in two ways. ALL of the conversations, in fact, has helped bring me to these conclusions.
1. I better see what is causing me concern. The industry indicates one thing, and the exam (understandably) reflects another. So when I came on board replacing Mr. K, one of my Professors, over ten years ago, antiquated tests were and are still on the board exam. I felt obligated to teach them in both lecture and labs. Since hearing all of the responses, I will scale back to mentioning them with the possibility of a level I (recall) question on an exam.
2. Your response also offers a more systematic approach to the problem. To date, updates to my curriculum have been ad hoc, but the five-year interval, which coincides with the lifespan of hospital instruments, is a much better idea.
Gee, just as I am posting, I see Ryan's response, but the better judgment, with mixed feelings, tells me it is time to focus on the more pressing needs in the profession.
