What is the difference of tuberculin to insulin syringe in terms of measurements?

They are made for administration of specific measurements of either insulin or the antigen for TB testing called PPD (Purified Protein Derivative). Both types of syringes are calibrated into "units". Unit measurements are fixed measures but specific to each type of medicine/solution as to their volume. A unit of insulin is not the same thing as a unit of TB antigen, so the TB syringe can not be used in the place of an insulin syringe.
Insulin is administered with the insulin syringe "subcutaneously" (under the skin) in the subcutaneous (sub Q) tissue. The needle is slightly longer than that on a TB syringe. The antigen solution is administered in the TB test "intradermally" (within the skin/between the layers of the skin) instead of under the skin, so the needle is shorter.
The amount of liquid in a dose of TB antigen is much smaller than the amount usually given of insulin. Therefore, the barrel of the TB syringe is smaller in diameter to allow such very small amounts (drops) of antigen to be measured.
In addition, insulin syringes come in two scales of measurement: U-100 and U-40. This on the label of the syringes indicates which type of insulin they are made to measure and administer. The insulin vial will also be marked either "U-100" or "U-40". One strength is 100 units of insulin per mL and the other is 40 units of insulin per mL. A different insulin syringe is need to measure U-100 than the type used to measure U-40. Unit calibration on the syringe used must be matched to the "strength" of the insulin being used. U-100 insulin has 1/100 of a mL volume per unit (equal also to 1/100 of a cc). U-40 insulin has 1/40 of a mL volume per unit.

∙ 14y agoISMP and the Pennsylvania Patient Safety and Reporting System have received several reports describing errors in which tuberculin syringes were used in place of insulin syringes (Figure 4). Examples include a nurse who selected a tuberculin syringe instead of an insulin syringe and administered 0.9 mL (90 units) of insulin, which resulted in a tenfold overdose. In other cases, 1 patient received 60 units of insulin instead of 6 units; another patient received 40 units of insulin instead of 4 units.

Can 0.25 ml be measured in a tuberculin syringe?
It can be measured using tuberculin syringe 1 ml.
Do you use a tuberculin syringe to give flu shots?
No, a tuberculin syringe is intended for use in intradermal injections and the flu shot is given intramuscularly. The needle on a tuberculin syringe is not the right size.
How do you read a tuberculin syringe?
To read a tuberculin syringe you simply have to look at the calibrations on the syringe. Make sure that your eye is level to avoid taking a wrong reading as a result of parallax.
Is there ISO Specification for Tuberculin Syringe labelling?
NO
What is the standard calibration of a tuberculin syringe?
0.1mL
Is the tuberculin syringe used to measure doses larger than 3 ml?
NO. A tuberculin syringe will only hold up to one ml. It is very useful, and appropriate for measuring any amount equal to or less than one ml. Also...It is NOT appropriate to try to use an insulin syringe for this purpose, as some people try to do. Insulin syringes are measured in *units*, not milliliters and therefore will not give an accurate reading of ml's. This is a potentially dangerous practice. If you have no other option...100 units = 1ml approximately...or so I am told. Get the right tool for the job!! Insulin needs to be measured accurately each and every time. It is not worth risking your life. Get the right syringe for administrating insulin!!

Tuberculin syringe is calibrated in blank of a cc?
1/100
You have a 3ml syringe and need to give 0.05cc of insulin How much do i draw up in units?
only use a insulin syringe for insulin. insulin MUST be correct.
Best unit to measure a teardrop?
Teardrops can vary widely in volume, but if you must know , collect the teardrop in a med cup , draw it up into an insulin or tuberculin syringe and convert the measurement of minims or cc's , into the desired measurement .
What type of syringe is used to administer 0.5ml of amoxicillin pediatric drops?
tuberculin 1ml
If using a tuberculin syringe instead of insulin syringe-how much insulin should i draw up?
Do not use a TB syringe for your insulin. The standard these days is for insulin to be 100 units per mL, which would seem to measure the same, but the syringes are calibrated differently and they are not always equivalent. There's a high likelihood you'll take too much or too little, and this deficit or excess can really add up if you're taking insulin a few times per day. If you're not sure, take your insulin and your syringes to your doctor, a local urgent care, or maybe a pharmacy and get help from a professional; it's too easy to overdose or underdose if you don't understand your medication.
