* We Have ready made, lyophilized, dry powder formed calibrator with two different concentration of D-DIMER. See photograph {{:nchsls:c:biochemistry:document:2ddimer.jpeg?400|}} {{:nchsls:c:biochemistry:document:3200.jpeg?400|}} {{:nchsls:c:biochemistry:document:5420.jpeg?400|}}
   -  3200 ng/ml
   -  5420 ng/ml
  * We are using Normal Saline (NS) for reconstitution purpose.
  * For reconstitute the Calibrator with 3200 ng/ml concentration, add 1 ML of NS into dry calibrator. So resulted concentration will be of 3200 ng/ml.
  * For reconstitute the Calibrator with 5420 ng/ml concentration, add 1700 uL of NS into dry calibrator. So resulted concentration will be of 3200 ng/ml.
  * This is our stock solution.
  * **__How to make QC:-__**
  * We decided to make QC of 800 ng/ml concentration from this stock solution.
  * For making such QC, take 800 uL of stock solution.
  * Add 2200 uL of Normal Saline.
  * Total volume will be of 3000 uL (3 ML).
  * From this 3 ml, Make cups of 200 uL.
  * 15 cups will be made.
  * Use these cups as QC.
