The proportion of “national blood” in domestic blood-derived products would be ratcheted up over the next few years to reduce dependence on foreign sources and reinforce Taiwan’s medical resilience, the Food and Drug Administration (FDA) said on Saturday.
The Ministry of Health and Welfare has announced a development program, saying that domestic plasma demand would rise to 170 tonnes next year from 140 tonnes, with growing demand for immunoglobulins, albumin and factor VIII.
Although Taiwan currently has sufficient blood supply, it has long relied on imports for blood-derived products, it said.

As foreign blood products carry the risks of contracting foreign infectious diseases and running short of supply during emergencies, securing “national blood” — blood donated by Taiwanese and its derived products — for domestic use is crucial, the ministry said.
FDA Deputy Director-General Wang Te-yuan (王德原) said the ministry’s data on projected demand were derived from reported usage under the National Health Insurance program and the number of blood products’ lot releases.
Increasing the proportion of domestic blood products is significant, as import shortages could occur during wars or pandemics due to other countries’ export controls, he said.
As Taiwan has yet to have a blood product manufacturer, the government has since 2007 allowed the Taiwan Blood Services Foundation to commission CSL Behring to produce national blood-based products in Australia, Wang said.
Of the total of 71 licenses approved for blood products circulated in Taiwan, two immunoglobulin licenses and an albumin license are for national blood-derived products, while the others are for those manufactured based on non-national blood, he said.
Currently, immunoglobulins derived from national blood plasma account for only half of the domestic demand, while albumin contributes to a still lower proportion of less than 10 percent, Wang said.
Foreign plasma products might not be as efficacious as those based on national blood plasma due to epidemiological differences, he said, adding that boosting national blood-derived products is the key to solid medical resilience.
The FDA announced draft amendments to Blood Donors’ Health Standards (捐血者健康標準) on Oct. 24 last year, which would raise donor age eligibility to 70 and relax body weight limits, with expectations that more blood would be donated to increase the percentage of national blood-derived products, Wang said.
Taiwan Society of Blood Transfusion executive director Lo Shih-chi (羅仕錡) said that clinical indications of immunoglobulin continue to expand and its usage increases every year, making it one of the most important blood products for treating autoimmune diseases, such as thrombocytopenia and systemic lupus erythematosus.
Albumin and factor VIII usages have been relatively stable and are recommended for people with liver diseases and hemophilia, he added.
Taipei Blood Center planning division director-general Liu Chun-hung (劉俊宏) said each pack of donated blood can be separated into plasma and red blood cells.
Plasma extracted from national blood is estimated to be enough to meet next year’s extra 30 tonnes of plasma demand, as red blood cells are in higher demand while plasma is largely left in storage, he said.
The Coast Guard Administration (CGA) and Chunghwa Telecom yesterday confirmed that an international undersea cable near Keelung Harbor had been cut by a Chinese ship, the Shunxin-39, a freighter registered in Cameroon. Chunghwa Telecom said the cable had its own backup equipment, and the incident would not affect telecommunications within Taiwan. The CGA said it dispatched a ship under its first fleet after receiving word of the incident and located the Shunxin-39 7 nautical miles (13km) north of Yehliu (野柳) at about 4:40pm on Friday. The CGA demanded that the Shunxin-39 return to seas closer to Keelung Harbor for investigation over the
National Kaohsiung University of Science and Technology (NKUST) yesterday promised it would increase oversight of use of Chinese in course materials, following a social media outcry over instances of simplified Chinese characters being used, including in a final exam. People on Threads wrote that simplified Chinese characters were used on a final exam and in a textbook for a translation course at the university, while the business card of a professor bore the words: “Taiwan Province, China.” Photographs of the exam, the textbook and the business card were posted with the comments. NKUST said that other members of the faculty did not see
The Taipei City Government yesterday said contractors organizing its New Year’s Eve celebrations would be held responsible after a jumbo screen played a Beijing-ran television channel near the event’s end. An image showing China Central Television (CCTV) Channel 3 being displayed was posted on the social media platform Threads, sparking an outcry on the Internet over Beijing’s alleged political infiltration of the municipal government. A Taipei Department of Information and Tourism spokesman said event workers had made a “grave mistake” and that the Television Broadcasts Satellite (TVBS) group had the contract to operate the screens. The city would apply contractual penalties on TVBS
An apartment building in New Taipei City’s Sanchong District (三重) collapsed last night after a nearby construction project earlier in the day allegedly caused it to tilt. Shortly after work began at 9am on an ongoing excavation of a construction site on Liuzhang Street (六張街), a neighboring apartment building tilted and cracked, leading to exterior tiles peeling off, city officials said. The fire department then dispatched personnel to help evacuate 22 residents from nine households. After the incident, the city government first filled the site with water to stabilize the groundwater level and then added dirt and cement to
