Lately I have been receiving patients who want to know if they have developed protection against Covid-19 after they have been vaccinated. We are offering them to do SARS-CoV-2 IgG and IgM spike or nucleocapside depending on the vaccine. But if still it hasn´t been approved to consider results in order to know the effectiveness of the vaccine, what advice can you give me? Here in Mexico City people are afraid that they didn´t received a good vaccine because of temperature, application, content, etc.
Would participants mind sharing their Potassium critical low cutoff values. Arrhythmogenicity of high potassium levels is well documented and while posting this I am searching through PUBMED about the same for low potassium levels.
As most of you are aware that there is an increase in the use of sodium nitrite as a suicidal agent. I was wondering what everybody was using for QC material for the analysis of methemoglobin. Is there a commercial source for this, especially for elevated amounts (the RNA QC does have a methemoglobin, but all three levels are normal)? Any and all help would be appreciated.
