How to Pronounce Kleihauer
"In the lab, we performed the Kleihauer-Betke test to detect fetal red cells in maternal blood."
"The clinician cited a positive Kleihauer result to assess the extent of fetal-metal hemorrhage."
"Kleihauer is rarely used outside obstetrics and transfusion medicine."
Pronounce as KLEE- how- er with primary stress on Klei. IPA US: /ˈkliːˌhaʊər/; UK/AU: /ˈkliːˌhaʊə(r)/. Break it into three parts: Klei (like “clay” without y), -hau- (rhymes with “how”), -er (schwa + r, lightly pronounced in rhotic accents). You’ll want a crisp onset, a clear long E, and a rounded diphthong in the second syllable. Practice slowly: /ˈkliː/ + /ˈhaʊ/ + /ər/.
Common errors: 1) Slurring the middle -hau- into -how- too quickly, making /ˈkliːˈhaʊər/ sound fused; 2) Misplacing stress, giving non-native listeners a flat first syllable; 3) Not finishing with the rhotic -er, especially in US non-rhotic speech. Correction: stress the first syllable and articulate the second with a clear /aʊ/ diphthong, then end with a light /ər/ in rhotic accents or /ə/ in non-rhotic. Tweak timing so each part remains distinct.
US speakers tend to pronounce final -er as /ɚ/ with rhoticity, giving /ˈkliːˌhaʊɚ/. UK/AU speakers often reduce the final to /ə/ or /ə/ with less pronounced rhoticity, yielding /ˈkliːˌhaʊə/. The middle -hau- consistently uses /aʊ/ as in “how.” The main differences are rhoticity and vowel quality in the final syllable; the onset and middle syllables are similar across regions.
The difficulty lies in the three-syllable structure with a long mid-vowel cluster and a final rhotic or reduced vowel. The /ˈkliː/ onset couples a long E with a tense L sound, the /ˈhaʊ/ middle requires an accurate /aʊ/ diphthong, and the final /ər/ or /ə/ can be tricky if you’re not used to linking or pronouncing final r-s in English. Practice helps you stabilize the timing and the tongue position.
One distinctive feature is the clear separation between syllables with minimal liaison. Do not blend Klei- with -hauer; keep a distinct pause-like separation so each syllable remains audible. In careful speech, you should avoid elision: /ˈkliːˌhaʊər/ remains three clear parts, especially in clinical reports where precise pronunciation improves understanding. This makes your delivery sound deliberate and professional.
🗣️ Voice search tip: These questions are optimized for voice search. Try asking your voice assistant any of these questions about "Kleihauer"!
US: emphasize rhotic final /ɚ/ or /ər/; UK/AU: reduce final /r/ to /ə/ or silent; the middle /haʊ/ remains the same with /aʊ/. Vowel refinement: ensure /iː/ and /aʊ/ are clearly distinct; use a tense /iː/ and a rounded /aʊ/ glide. Consider linking and rhythm differences: US tends to link more, UK/AU separate syllables more distinctly.
Kleihauer traces to the surname of two German scientists, Felix Kleihauer and Eva Betke, who developed a method for detecting fetal red blood cells in maternal blood in the 1950s. The term combined their names as a proper noun and was later adopted to label the procedure they described, the Kleihauer-Betke test. The underlying idea involves differentiating fetal hemoglobin-containing cells from maternal cells using acid elution and staining, allowing observers to visualize dark-staining fetal cells amidst pink maternal cells. Over time, the assay became a staple in obstetric transfusion medicine for quantifying fetomaternal hemorrhage, especially after events like traumatic delivery or placental abruption. The word is now widely recognized in medical literature and clinical practice, though outside the profession it remains an obscure term, often encountered in specialized articles and hospital reports. The original spelling honors its discoverers, and the compound “Kleihauer-Betke” reflects the collaboration between the scientists who introduced the test and the method’s dual genetic naming convention. Today, the term is used almost exclusively in hematology and obstetrics, and the root concept—detecting fetal cells in maternal blood—remains its central meaning and application.
