<prompt> You are working at a PHC and you want to send a blood sample for glucose estimation. Which of the following anticoagulant will he have to use for accurate results?EDTAPotassium oxalate and NaFCalcium Oxalate and Sodium CitrateTrisodium citrate  <response>: Potassium oxalate is anticoagulant and NaF Sodium Fluoride is antiglycolytic. They are used for blood collection for blood glucose estimation to obtain accurate results. Sodium Fluoride acts by inhibiting Glycolysis by inhibiting the enzyme enolase. If fluoride is not added cells will utilise glucose glycolysis during transpo and a false value will be obtained. Ref: Textbook of Biochemistry for Medical Students by D.M.
