If so, the principle stays the same—just look for the major numbers marked on the syringe, and count the smaller marks in between. Measure in between the hash marks, if necessary. Sometimes you will be asked to measure an amount that is not exactly marked by the hash lines on your syringe. To do this, you'll have to count between the lines. For instance, say you have been asked to measure 3.
Pull the medication up the syringe and then push the plunger down until the medication is between the 3. Part 2. Hold the syringe by its flange. Grasp the syringe by the winged parts located on the end of the syringe opposite from the tip. This is known as the flange.
Holding the syringe this way makes it so your fingers won't be in the way while you try to read the syringe. For everyday measurements like home medications , you don't need to worry about body heat distortion.
Over-fill the syringe. Always use a syringe that is larger than the amount you need to measure. Insert the needle into the liquid you want to measure, then slowly pull back on the plunger until the syringe is filled past the mark for the amount you need to measure. Pull the plunger back until the liquid fills the syringe past the 3 mL mark. Release the plunger until it is at the mark you need to measure by. Still holding the syringe in your hand, slowly push down on the end of the plunger with your thumb until its edge is even with the point you need to measure by.
Read from the top ring of the plunger. No matter what syringe you use, always look at the part of the plunger closest to the tip when reading it. This will be the part touching the liquid that you are measuring. The part of the plunger closest to the top of the syringe is irrelevant and not meant to be used for measuring [5] X Research source.

If you are administering insulin you will use a syringe that measures in units. If the top ring of the plunger rests three large lines and four small lines from the top line of the syringe body, then there are 0. Draw liquid into the syringe by inserting either the tip or the needle into the liquid and pulling the plunger upward. Turn the syringe so that the tip or needle points upward and you see the numbers at the side of the syringe in proper position.
Note the position of the plunger ring closest to the needle or tip and the number to which it is the closest. Remember that the line closest to the tip itself is the zero line. Three lines below the "3" mark equal 3. Four lines below the top mark equal 0. Draw liquid into the syringe by inserting either the tip or the needle into the liquid and pulling the handle upward. Note the numbered line closest to which the plunger ring nearest to the tip of the syringe rests.
Add 1 mL for each line below it and above the next numbered line. If the top of the plunger rests three lines down from the line marked "5," then there are 8 mL of liquid in the syringe.
If it rests two lines down from the line marked "15," then there are 17 mL of liquid in the syringe. Do not attempt to read insulin syringes using this information.
