In this test, a standardized solution made with purified protein derivative (PPD), which is derived from tuberculin, is injected under the skin. Typically, PPD produces a T-cell mediated delayed-type hypersensitivity reaction if the person has been infected with TB bacteria.

The Mantoux test or Mendel–Mantoux test (also known as the Mantoux screening test, tuberculin sensitivity test, Pirquet test, or PPD test for purified protein derivative) is a tool for screening for tuberculosis (TB) and for tuberculosis diagnosis.

2025年2月24日 · If you're curious about how to read a tuberculosis skin test, this article will guide you through the process, but remember: the test must be read by a trained professional. You can interpret the test yourself, but the result needs to be documented by a medical professional to ensure proper treatment and/or follow-up.

The TST is performed by injecting 0.1 ml of tuberculin purified protein derivative (PPD) into the inner surface of the forearm. The injection should be made with a tuberculin syringe, with the needle bevel facing upward. The TST is an intradermal injection.

2023年4月23日 · PPD Skin Test Interpretation Based on CDC Guidelines. The result of the PPD test is either positive or negative. However, the size of the induration diameter cutoff (5, 10, or 15 mm) for the test to be considered positive is based on certain risk factors.

This annex describes how to administer, read and interpret a TST using 5 tuberculin units (TU) of tuberculin PPD-S. An alternative to 5 TU of tuberculin PPD-S is 2 TU of tuberculin PPD RT 23.

PostScript Printer Description (PPD) files are created by vendors to describe the entire set of features and capabilities available for their PostScript printers. A PPD also contains the PostScript code (commands) used to invoke features for the print job.

PostScript Printer Description ("PPD") files describe the capabilities of each printer and are used by CUPS to support printer-specific features and intelligent filtering. The PPD format is text-based and uses lines of up to 255 characters terminated by a carriage return, linefeed, or combination of carriage return and line feed.

2018年9月17日 · A purified protein derivative (PPD) skin test is a test that determines if you have tuberculosis (TB). TB is a serious infection, usually of the lungs, caused by the...

2024年11月23日 · The Purified Protein Derivative (PPD) skin test, also known as the Mantoux tuberculin skin test, remains a cornerstone in tuberculosis (TB) screening worldwide. Despite newer blood-based tests, the PPD test continues to be widely used due to its accessibility, cost-effectiveness, and established reliability.
