What causes elevated partial thromboplastin time?

Coagulation, Thrombosis, Hemostasis

The elevated partial thromboplastin time can be attributed to the following factors:

1. Drug and Dietary Influences:

The intake of certain medications, injection of drugs, or consumption of specific foods can interfere with test results.

2. Improper Blood Collection:

During venipuncture, improper techniques such as excessive squeezing or suction can disrupt blood circulation, trigger the body's coagulation pathways, deplete coagulation factors, and thereby alter the endogenous coagulation function.

3. Pathological and Physiological Conditions:

In cases of various blood diseases and other pathological or physiological states, the partial thromboplastin time may be prolonged. If such an elevation occurs, it is crucial to seek medical attention promptly without delay.

Thromboplastin is a key indicator in coagulation function tests, reflecting the body's endogenous coagulation ability. When the thromboplastin index shows an increase, if the time increase is less than or equal to three seconds, it typically holds no significant medical implications. However, if the time increase exceeds three seconds, it indicates a decline in the body's endogenous coagulation function.

Beijing Succeeder Technology Inc. (Stock Code: 688338), established in 2003 and listed in 2020, is a prominent player in the field of coagulation diagnostics. We specialize in manufacturing automated coagulation analyzers and reagents, ESR/HCT analyzers, and hemorheology analyzers. Our products have obtained ISO 13485 and CE certifications, and are used by over 10,000 users globally.

Analyzer Introduction

Fully Automated Coagulation analyzer SF-9200 (https://www.succeeder.com/fully-automated-coagulation-analyzer-sf-9200-product) is designed for clinical testing and pre-operative screening. It is also utilized by hospitals and medical researchers. This analyzer employs coagulation, immunoturbidimetry, and chromogenic methods to assess plasma clotting. The instrument presents the clotting measurement as clotting time, with the unit being seconds. When the test item is calibrated using calibration plasma, additional relevant results can be displayed.

The product consists of a sampling probe movable unit, cleaning unit, cuvettes movable unit, heating and cooling unit, test unit, operation-display unit, and an LIS interface (used for connecting to a printer and transferring data to a computer).

Our team of skilled and experienced technicians, combined with high-quality analyzers and strict quality management measures, ensures the production of the SF-9200 with top-notch quality. Each instrument undergoes rigorous inspection and testing. The SF-9200 complies with China's national standards, industry standards, enterprise standards, and IEC standards.
