The answers were relatively predictable...

Julie wrote: "I was wondering if there was a list of the specific disease states and the correction factors involved.  For example, if a specimen was corrected by the addition of normal pooled plasma, but the Russell viper venom test was abnormal, what disease state would this indicate?  It would be nice to have a chart for quick reference." It occurred to me that we need a summary of presumed acquired and congenital coagulation deficiencies related to prothrombin time (PT) and partial thromboplastin time (PTT) results in bleeding patients. Here is a table that may be useful... Wed, 20 Aug 2008 00:00:00 -0400 http://www.fritsmafactor.com/blog.php?bid=179 http://www.fritsmafactor.com/blog.php?bid=179 Good afternoon,  I have been referred to you to ask about Factor V.  After my sisters tested positive for this blood disorder I took the test for Factor V and was told that my count was 2.49.  My family physician is not familiar with this disorder.  I would like to know if this number means that I tested positive  for this condition, or am I negative?  What should my next step be?  Should I make an appointment with a hemotologist?  I would really appreciate your opinion, as I am told you are quite familiar with Factor V. Thank you so much for your time.  Sincerely, Jan Scott Tue, 19 Aug 2008 00:00:00 -0400 http://www.fritsmafactor.com/blog.php?bid=178 http://www.fritsmafactor.com/blog.php?bid=178 George: I was looking at different coagulation methods, possibly doing factor testing and mixing studies.  We are looking at various instruments, one being the ACL TOP.  I was wondering if there was a list of the specific disease states and the correction factors involved.  For example, if a specimen was corrected by the addition of normal pooled plasma, but the Russell viper venom test was abnormal, what disease state would this indicate?  It would be nice to have a chart for quick reference.  Thanks for your time.

FFP is supernatant plasma expressed from centrifuged whole blood and frozen within eight hours of collection. However, FFP usage is diminishing as we change to FP24. What is FP24?

Please send a reply giving your laboratory's volume so she can extrapolate to estimate a nationwide volume. Thank you. Jennifer: thanks to Stephen Duff at Precision Biologic, we've located a CDC report on laboratory testing volumes. Click on http://wwwn.cdc.gov/mlp/coagulation_resources.aspx, it should bring you there.

She is converting her central lab and a number of satellite labs from MDA to Beckman-Coulter Inc. (BCI, TOP) instrumentation, and most recently is moving her factor V and VII activity levels to the new instrument and reagents. Factors V and VII assays are based on the prothrombin time reagent, and although it is rare to have a single factor V or VII deficiency, they are often assayed to confirm liver disease and to distinguish the coagulation effects of liver disease from vitamin K deficiency.Anyway, her problem is this...

I look forward to seeing your answers, and encourage you to submit quick questions for a survey also.

De Vito In reading an article, Quote: The INR is a standardized number and is calculated from the patient PR, the normal range for PT, and the sensitivity of the reagent used.   Please explain to me the following: (1) The patient PR(2) Normal range for PT(3) Reagent usedI will await your reply. Thanking you. I remain, respectfully, Joseph A. De Vito Thu, 24 Jul 2008 00:00:00 -0400
