The Internet loves cats. There's no denying it. And we're happy to ride that wave of enthusiasm here at Westgard Web. But in our case, we want to talk about the fluffy cute adorable biologic variation of plasma analytes in cats. (more after the jump)
A paper was recently published that extended the biologic variation studies into the world of cats:
Biological variation and reference change values of feline plasma biochemistry analytes, Baral RM, Dhand NK, Freeman KP et al, Journal of Feline Medicine and Surgery, online first, November 11, 2013.
This is the first study that covers biologic variation of biochemistry parameters in cats. Here's short except, and what we're adding here is the human biologic variation as well, as recorded in the biologic variation database.
in the table below, CVg stands for within-group biologic variation, while CVw stands for within-subject biologic variation. Sometimes CVi is used to mean the same thing as CVw.
6.0
Analyte | Feline CVg | Feline CVw | Human CVg | Human CVw |
Albumin | 3.88% | 3.0% | 4.2% | 3.1% |
Calcium | 2.51 | 2.34 | 2.8 | 1.9 |
Chloride | 1.16 | 1.17 | 1.5 | 1.2 |
Cholesterol | 22.35 | 10.74 | 15.2 | 5.4 |
Creatinine | 11.43 | 5.97 | 14.7 | 6.0 |
Glucose | 8.06 | 6.76 | 5.8 | 4.5 |
Sodium | 0.57 | 0.86 | 1.0 | 0.7 |
This table only shows a subset of all the analytes from the study. which covers 20 different parameters. But it's certainly interesting to see how similar to (and sometimes, how different from) our feline friends.
The whole study is well worth a read.
I feel honoured that you have noticed my paper since I have drawn much inspiration and knowledge from your website (and books!).
