Doctor saab, please don’t take things personally and this post certainly is not intended to be. I am going to counter your points one by one since I don’t think you have got a clue about laboratory medicine:
Ya I am from medical background. –
But you are purely a clinician with no laboratory background and don’t know how lab science works! Vast majority of clinicians are like that except for a few who specialises in biochemistry, haematology or microbiology. Most clinicians don’t realise the importance of quality of results and accuracy etc. Most local labs still don’t have quality assurance programs in place – this is costly and recurring exercise and hence skipped by most labs.
Glucose is measured with fluoride . But even after 1 hour delay there is a decrease in glucose content. 10% difference is massive.
Clear that you don’t know why fluoride is used. Blood is taken in a tube with fluoride in it which will inhibit glycolysis and which prevents consumption of glucose (so the sample could be stored or transported for testing later). You probably assumed the claim made by Weblinsolutions that 10% variation is true. Wrong assumption again (variation depends on the test). You are a doctor, so please do not believe the hearsay!
For HbA1C when up 5.8 it’s pre diabetic but 6.4 is diabetic
HbA1C is not measured in the same way as glucose and also 10% variation is too much variation for HbA1C. Inter-lab or intra-lab variation for HbA1C should be <3% (if more than 3% then the result from one lab is wrong and will usually be the local lab with no quality controls)
IN periphery ask any doctor if they will trust the thyrocare results
Unfortunately Thyrocare does not give kick-backs to doctors and hence they are not popular with doctors! If doctors truly care about their patients (quality of the tests/results and at a very cheap price) they should refer patients to thyrocare! Local labs (vast majority of them) quality of work is poor and their results unreliable.
If central lab is so economical then why are Lal path and everybody else having so many labs.
You should be asking this question to Dr Lal. Thyrocare has limited array of tests and Dr Lal has a wide spectrum. Thyrocare is focused and Dr lal diversified.
I am also a clinician, I also work in the lab.
