Caught by LOOKING at the live page on 2026-07-30, right after\n   the template was switched to canvas.\n\n   Everything is scoped to `.bp-adv`, so nothing here can reach the rest of\n   bioprofile.com, and core blocks are styled BY ELEMENT so a heading, a\n   paragraph, a quote, a list, an image or a button inserted by hand inside the\n   advertorial comes out on-design with no class to remember.\n\n   Jesse's design feedback, 2026-07-29 23:38, point by point:\n   1. the light green and the dark green are the preferred colours; grey may be\n      used but the page must NOT open grey;\n   2. more colour and variation across sections, e.g. a colour block on the left\n      or the right side of a section, without overdesign;\n   3. ONE H1, plain text on white; everything else H2 or H3; an H2 may carry its\n      own background colour so the page can be read from the headings alone; an\n      H3 keeps its section background and gets a bigger font size;\n   4. reuse the results page design feel;\n   5. Written by \/ Verified by, the placeholder blocks and noindex stay.\n\n   COLOUR PROVENANCE. Not one hex is invented.\n   - #b7cb32  LIGHT GREEN, brand manual \"colours rejuvenation protocol\"\n              (R183 G203 B51). Same value as --bp-lime in\n              brands\/bioprofile\/brand\/tokens.md.\n   - #006b62  DARK GREEN, brand manual, nourish the cells (R0 G107 B98).\n   - #005859  brand manual primary teal, the value the brand is built on.\n   - #228a62  brand manual, challenge the body (R34 G138 B98).\n   - #7ca64c  brand manual, calm the mind (R124 G166 B76).\n   - #dbd4cd  brand manual \"additional color\", the warm neutral.\n   - #B7CB3329 is the brand token --bp-lime-soft (light green at 16 percent).\n   - the gradients are the brand token layer's own, copied verbatim.\n\n   SPECIFICITY NOTE. Elementor's global kit emits `.elementor-kit-6 h2` style\n   rules at (0,1,1). Element rules below are written `.bp-adv h2`, also (0,1,1),\n   and win on source order because this sheet is inline in the body while the\n   kit is a <link> in the head. Component rules that MUST NOT lose carry two\n   classes, e.g. `.bp-adv .wp-block-button__link`.\n\n   LAYOUT NOTE. Vertical rhythm uses `margin-block` and never the `margin`\n   shorthand, so the measure rule `.bp-adv-sec > * { margin-inline: auto }` can\n   centre a block without being outranked by its own element rule.\n   =========================================================================== *\/\n\n.bp-adv {\n  --bp-ink: #212527;\n  --bp-teal: #005859;\n  --bp-forest: #006B62;\n  --bp-emerald: #228A62;\n  --bp-olive: #7CA64C;\n  --bp-lime: #B7CB33;\n  --bp-lime-soft: #B7CB3329;\n  --bp-sand: #DBD4CB;\n  --bp-white: #FFFFFF;\n  --bp-foot: #6b6b6b;\n  --bp-grad-dark: linear-gradient(237deg, rgba(0,88,89,0.00) 62.94%, #005859 100%), linear-gradient(90deg, rgba(34,138,98,0.00) 40%, #228A62 100%), #006B62;\n  --bp-grad-lime: linear-gradient(110deg, rgba(183,203,51,0.00) 36.06%, rgba(183,203,51,0.25) 97.65%), #FFFFFF;\n  --bp-font: 'Poppins','Segoe UI',Arial,sans-serif;\n  --bp-fs-h1: 44px; --bp-fs-h2: 31px; --bp-fs-h3: 24px; --bp-fs-pre: 15px;\n  --bp-fs-body: 17px; --bp-fs-small: 14px; --bp-fs-foot: 13px; --bp-fs-btn: 17px;\n  --bp-lh-body: 1.75;\n  --bp-s-1: 4px; --bp-s-2: 8px; --bp-s-3: 12px; --bp-s-4: 16px;\n  --bp-s-5: 24px; --bp-s-6: 32px; --bp-s-7: 44px; --bp-s-8: 72px;\n  --bp-measure: 760px; --bp-side: 40px;\n  --bp-radius-photo: 16px; --bp-radius-btn: 10px; --bp-radius-card: 20px;\n  --bp-shadow: 0 10px 30px rgba(0,88,89,0.10);\n  font-family: var(--bp-font);\n  font-size: var(--bp-fs-body);\n  line-height: var(--bp-lh-body);\n  color: var(--bp-ink);\n  background: var(--bp-white);\n  -webkit-font-smoothing: antialiased;\n}\n.bp-adv, .bp-adv * { box-sizing: border-box; }\n.bp-adv p, .bp-adv li, .bp-adv h1, .bp-adv h2, .bp-adv h3, .bp-adv blockquote,\n.bp-adv a, .bp-adv cite, .bp-adv span { overflow-wrap: break-word; min-width: 0; }\n\n\/* THE TOGGLE.

Einen Wert innerhalb der Grenzen bezeichnet das Labor als normal.<sup>[3]<\/sup><\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Der Referenzbereich von Labplusarts<\/h3>\n\n\n\n<figure class=\"wp-block-table bp-bm-table\"><table><thead><tr><th>Bereich<\/th><th>Was es bedeuten kann<\/th><th>F\u00fcr wen<\/th><\/tr><\/thead><tbody><tr><td>Keine Grenze in Zahlen (qualitative Bestimmung)<sup>[3]<\/sup><\/td><td>Einen Wert zwischen den Grenzen nennt das Labor normal<\/td><td>Vom Labor nicht n\u00e4her angegeben<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"bp-bm-caption wp-block-paragraph\">Quelle: Labplusarts, Referenzwert f\u00fcr Immunglobulin A (IGALG), wie das Labor ihn verwendet.<sup>[3]<\/sup><\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Immunglobulin A zu niedrig<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Ein niedriger Wert eines oder mehrerer Immunglobuline kann auf etwas hinweisen, wodurch Ihr K\u00f6rper Eiwei\u00df verliert oder zu wenig aufnimmt. Das kann etwa eine Erkrankung der Nieren sein, schwere Verbrennungen, ein Darm, der Nahrung schlecht aufnimmt, oder Mangelern\u00e4hrung. Er kann auch auf etwas hinweisen, wodurch Ihr K\u00f6rper weniger Antik\u00f6rper bildet, zum Beispiel Nieren, die nicht mehr gut arbeiten, oder eine angeborene Erkrankung des Abwehrsystems.<sup>[1]<\/sup><\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Immunglobulin A zu hoch<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Ein hoher Wert kann auf eine Erkrankung hinweisen, bei der das Abwehrsystem k\u00f6rpereigene Zellen angreift, auf eine Erkrankung der Leber, auf einen Krankheitserreger, der lange im K\u00f6rper bleibt, oder auf bestimmte Erkrankungen des Knochenmarks, des Blutes oder des Abwehrsystems. Diese Antik\u00f6rper wirken dann oft nicht gut, sodass Sie auch mit einem hohen Wert h\u00e4ufig krank werden k\u00f6nnen. Ein abweichender Wert muss nicht immer bedeuten, dass etwas vorliegt, das medizinische Versorgung braucht. Besprechen Sie Ihr Ergebnis mit Ihrer medizinischen Fachperson.<sup>[1]<\/sup><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">BioProfile arbeitet an eigenen Zonen pro Wert, von Risiko bis optimal.

Alles, wodurch Ihr K\u00f6rper Eiwei\u00df verliert oder zu wenig Nahrung aufnimmt, etwa Mangelern\u00e4hrung oder ein Darm, der Nahrung schlecht aufnimmt, kann Ihren Wert senken.<sup>[1]<\/sup><\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Vorbereitung<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Auf diesen Test m\u00fcssen Sie sich nicht besonders vorbereiten.<sup>[1]<\/sup><\/p>\n\n<\/div>\n\n\n\n<div class=\"wp-block-group bp-adv-sec bp-adv-sec--wash is-layout-flow wp-block-group-is-layout-flow\">\n\n<h2 class=\"wp-block-heading\" id=\"bp-welke-pakketten\">Welche BioProfile-Pakete Immunglobulin A messen<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Immunglobulin A ist in BioProfile 121 und 150 enthalten.<sup>[4]<\/sup><\/p>\n\n\n\n<div class=\"wp-block-buttons is-content-justification-center is-layout-flex wp-container-core-buttons-is-layout-3e41869c wp-block-buttons-is-layout-flex\">\n\n<div class=\"wp-block-button\"><a class=\"wp-block-button__link wp-element-button\" href=\"https:\/\/bioprofile.com\/de\/blutuntersuchung\/\">Die Pakete ansehen<\/a><\/div>\n\n<\/div>\n\n<\/div>\n\n\n\n<div class=\"wp-block-group bp-adv-sec is-layout-flow wp-block-group-is-layout-flow\">\n\n<h2 class=\"wp-block-heading\" id=\"bp-waarden-die-erbij-horen\">Werte, die dazugeh\u00f6ren<\/h2>\n\n\n\n<ul class=\"wp-block-list bp-bm-related\">\n\n<li><a href=\"https:\/\/bioprofile.com\/de\/biomarkers\/leukozyten\/\">Leukozyten<\/a>: z\u00e4hlt Ihre wei\u00dfen Blutk\u00f6rperchen, sodass Sie neben den Antik\u00f6rpern einen besseren Einblick in Ihr Abwehrsystem bekommen.<sup>[1]<\/sup><\/li>\n\n\n<li><a href=\"https:\/\/bioprofile.com\/de\/biomarkers\/lymphozyten\/\">Lymphozyten<\/a>: zeigt, wie viele der Abwehrzellen vorhanden sind, die \u00fcber Ihre Lymphfl\u00fcssigkeit durch den K\u00f6rper wandern.<sup>[1]<\/sup><\/li>\n\n\n<li><a href=\"https:\/\/bioprofile.com\/de\/biomarkers\/eosinophile\/\">Eosinophile Granulozyten<\/a>: zeigen neben IgA einen anderen Teil Ihres Abwehrsystems.<sup>[1]<\/sup><\/li>\n\n\n<li><a href=\"https:\/\/bioprofile.com\/de\/biomarkers\/monozyten\/\">Monozyten<\/a>: erg\u00e4nzt das Bild, das die Antik\u00f6rper geben, um eine andere Art von Abwehrzelle.<sup>[1]<\/sup><\/li>\n\n\n<li><a href=\"https:\/\/bioprofile.com\/de\/biomarkers\/neutrophile-granulozyten\/\">Neutrophile Granulozyten<\/a>: hilft zu erkennen, wie Ihr Abwehrsystem reagiert, wenn Sie h\u00e4ufig krank werden.<sup>[1]<\/sup><\/li>\n\n<\/ul>\n\n<\/div>\n\n\n\n<div class=\"wp-block-group bp-adv-sec bp-adv-sec--wash is-layout-flow wp-block-group-is-layout-flow\">\n\n<h2 class=\"wp-block-heading\" id=\"bp-hoe-gemaakt\">Wie diese Seite entstanden ist<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Die BioProfile Redaktion hat diese Seite am 10.
