The Standard Curve

Strategic thinking on in-vitro diagnostics — calibrating the conversation between East and West, from the Mexican bench.

About this notebook

I have spent sixteen years inside the in-vitro diagnostics business — long enough to have sold, specified, installed, defended, and occasionally apologised for instruments and reagents from most corners of the world. My vantage point is Mexico, which turns out to be one of the most honest laboratories on earth for a particular question: what actually happens when Asian and Western diagnostics meet in front of a buyer who has to live with the consequences.

The Standard Curve is where I write that question down.

The name is not decoration. In the lab, a standard curve is the quiet discipline that turns a raw instrument signal into a number a physician can trust. It is calibration — the act of relating what the machine says to what is actually true. Vendor marketing badly needs the same treatment. So does the lazy shorthand the industry still leans on: Western means quality, Asian means cheap. That sentence was already tired a decade ago. Today it is simply wrong, and acting on it costs laboratories real money and real uptime.

I am not a neutral party in the sense of having no opinions — I have many, and you will read them here. I am neutral in the sense that matters: I make my living helping institutions choose well, not helping any one manufacturer win. I work with brands from China, Japan, the United States, and Europe. I owe none of them my conclusions.

A few ground rules for this publication:

If you specify, buy, sell, regulate, or simply think about diagnostics for a living, this notebook is for you. Read it the way you would read any instrument output: with interest, and with the calibration curve in hand.
