Article : Only One Chance [about B12 deficiency & Pernicious Anaemia]

Well worth reading, in my opinion.

Title : Only One Chance

Introduction
It’s an old saying: “You’ve got only one chance to make a first impression”. This is true for many situations: when you meet your future spouse, or when you are in a job interview, or your first appearance as a player in a premier league game. Your future spouse will silently disappear if you talk too much about yourself or misbehave on your first date. And if you do not remember the company’s name where your job interview takes place, the chance of being selected as a new co-worker is zero. When you get a red card for a foul or score an own goal, not the best you can do in a first match.

Diagnosis obscured
In the situation of B12 deficiency, for instance, in the diagnostic process, there’s only one chance to make a first impression. Referring someone to a medical specialist with the specific question “The serum B12 is 240 pmol/l, is there B12 deficiency?”, directly after this person has received her first intramuscular B12 injection, is one first chance spoiled. After all, filling up someone’s body with 1000 micrograms of B12 will obscure proper diagnosis for the upcoming many months.

[ME and Long Covid both get a mention]
