1. what are the vitamins, minerals, amino acids , essential fatty acids for which lab measurement of serum/total body level available ? What are all available in the labs in India ? What is the cost-benefit ratio ?

2. Why Fat soluble amino acids are not mentioned anywhere in the texts of Fat malabsorbtion ? They only mention Vit ADEK deficiency....most of the Essential amino acids are fat soluble....is it not worth mentioning and treating???
