TB syringes are typically used for administering TB skin tests, holding 1 ml of fluid and marked in tenths of a milliliter. Insulin syringes are designed for injecting insulin, with capacity varying depending on concentration and marked in units. The main difference lies in their specific uses and the volume they are designed to accurately measure and deliver.
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.

They are used to deliver the antigen for tuberculosis tests to determine if a person is infected or has been infected with TB in the past. The TB skin test requires an intradermal injection of the antigen. The needle is the shortest and the syringe is the smallest so that the extremely small doses (drop size doses) of antigen can be delivered between the layers of the skin to create a blister/bleb that looks similar to a mosquito bite. The skin reaction to the antigen is measured for determining positive or negative reactions. They are also used for measuring and/or administering small amounts of medications, fluids, or solutions. For example, in neurosurgery, tuberculin syringes are used in the procedure to place Balcofen pumps into patients. The pumps deliver small amounts of anti-seizure medication into the spinal cord. In this usage, once the catheter is placed into the spinal cord, the TB syringe is used to remove a very minuscule amount of precious Cerebrospinal fluid (CSF) to make sure the catheter is patent (open). Insulin syringes are similar small syringes for administering insulin but not as small as TB syringes and the needles are for subcutaneous (sub-Q) use and slightly longer than TB syringe needles. The unit measures on the two types of syringes are not the same, so the two can not be interchanged for use.

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.
Surgical treatment of TB may be used if medications are ineffective.

TB Med stands for Technical Medical Bulletin. TB Med 530 is the Army regulation that governs dining facilities. It's used by Army health inspectors when they conduct health inspections.
Depends if heat is used
1 tb= 1000gb 10 tb= 10000gb
1.5 tb = 1 and a half tb
