serum
In medicine, a liquid obtained from blood that contains antibodies. It is used for vaccination or for treating diseases and poisoning.
Nach dem Schlangenbiss wurde dem Patienten sofort ein Serum verabreicht.
After the snake bite, the patient was immediately given a serum.
You can tell from the context whether a medical or cosmetic product is meant. Words like 'Arzt' (doctor), 'Impfung' (vaccination), or 'Antikörper' (antibodies) point to the medical meaning, while 'Haut' (skin), 'Gesicht' (face), or 'Pflege' (care/skincare) indicate cosmetics.
Dieses Serum versorgt die Haut mit Feuchtigkeit.
This serum provides the skin with moisture.
In the medical field, a serum is often 'verabreicht' (administered), 'gespritzt' (injected), or 'injiziert' (injected). Common compounds are 'Gegenserum' (antiserum, e.g. for poison) or 'Heilserum' (therapeutic serum).
Dem Wanderer wurde nach dem Biss ein Gegenserum gespritzt.
After the bite, the hiker was injected with an antiserum.
In cosmetics, a serum is typically 'aufgetragen' (applied) to the skin or 'einmassiert' (massaged in). Common terms are 'Gesichtsserum' (face serum), 'Feuchtigkeitsserum' (hydrating serum), or 'Anti-Aging-Serum' (anti-aging serum).
Sie trägt das Serum immer vor ihrer Tagescreme auf.
She always applies the serum before her day cream.
blood
'das Blut' and 'das Serum' are connected in medicine, but they are not the same thing. 'Blut' is the red fluid in the body. 'Serum' is a special liquid obtained from blood that can be used medically. Learners may confuse the words because serum can come from blood. Even so, in everyday language, you say 'Blut' when talking about an injury or a blood draw, not 'Serum'. 'Serum' fits better in medical or scientific situations.
Im Krankenhaus wurde ein Serum gegen das Gift vorbereitet.
In the hospital, a serum against the poison was prepared.
Nach dem Sturz lief Blut aus einer kleinen Wunde am Knie.
After the fall, blood was running from a small wound on his knee.
