87128-4

ISO 87128-4 is not a recognized or established standard or document as of my last update in October 2023. The ISO (International Organization for Standardization) typically uses a series number format, but this particular number—87128-4—does not appear to be associated with any known ISO standard. It's possible that you may be referring to a draft, an internal document, or a typographical error.
For accurate information, I recommend checking with the ISO's official database or the relevant organization associated with the standard or document in question. If this number pertains to a specific industry or field outside of ISO, please provide additional context, and I would be happy to assist further based on available information in that area.

The 87128-4 chip is an EPROM (Erasable Programmable Read-Only Memory) with a specific capacity and configuration. Equivalent products would include devices with similar memory size and architecture, such as the Intel 27128, AMD AM27128, or equivalents from manufacturers like Microchip or STMicroelectronics. When seeking an equivalent, ensure compatibility in terms of voltage, packaging, and access times. Always verify with datasheets for specific applications.

87128-4 refers to a LOINC code used in medical diagnostics. Specifically, it is associated with laboratory tests that measure the BCR-ABL1 (p210) fusion transcript in blood or bone marrow, typically using quantitative PCR methods. This test is crucial in the diagnosis and monitoring of chronic myeloid leukemia (CML) and Philadelphia chromosome-positive acute lymphoblastic leukemia (Ph+ ALL). It helps in assessing the level of residual disease, guiding treatment decisions, and monitoring response to therapy in patients undergoing treatment with tyrosine kinase inhibitors or other therapeutic strategies.

The package type for part number 87128-4 is typically associated with electronic connectors or components. To confirm the specific package type, you should refer to the manufacturer's datasheet or product documentation. This will provide detailed information on the packaging, including dimensions, materials, and intended use.
