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.

Sie besitzen winzige Filter, die Glomeruli. Diese entfernen Abfallstoffe und \u00fcbersch\u00fcssiges Wasser aus Ihrem Blut und leiten sie \u00fcber den Urin ab.<sup>[1]<\/sup><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Die Filterleistung direkt zu messen ist aufwendig und nicht \u00fcberall m\u00f6glich. Deshalb nutzen Fachleute meist eine Sch\u00e4tzung: die eGFR. Sie beginnt oft beim Kreatinin, einem Abbauprodukt, das durch den normalen Verschlei\u00df Ihrer Muskeln entsteht.<sup>[1]<\/sup><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Kreatinin allein reicht nicht aus, denn Menschen bilden unterschiedliche Mengen davon. Eine Rechenformel bezieht deshalb auch Ihr Alter, Ihr Gewicht, Ihre Gr\u00f6\u00dfe und Ihr Geschlecht mit ein. Manchmal wird Cystatin C verwendet, ein Eiwei\u00df, das nicht von Muskelmasse, Alter oder Ern\u00e4hrung abh\u00e4ngt.<sup>[1]<\/sup><\/p>\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-waarom-het-ertoe-doet\">Warum Ihre eGFR wichtig ist<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Eine Erkrankung der Nieren verursacht im fr\u00fchen Stadium meist keine Beschwerden. Eine eGFR kann sie dann trotzdem sichtbar machen. So k\u00f6nnen Sie und Ihr Behandlungsteam rechtzeitig \u00fcber die n\u00e4chsten Schritte sprechen.<sup>[1]<\/sup><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Ihr Risiko f\u00fcr eine Erkrankung der Nieren ist h\u00f6her, wenn Sie Bluthochdruck oder eine Erkrankung des Herzens haben, rauchen, \u00e4lter als 60 Jahre sind oder wenn Erkrankungen der Nieren in Ihrer Familie vorkommen. Fragen Sie dann Ihr Behandlungsteam, wie oft ein Test sinnvoll ist.<sup>[1]<\/sup><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In einem sp\u00e4teren Stadium kann eine Erkrankung der Nieren durchaus Beschwerden verursachen. Dazu geh\u00f6ren Schwellungen an Beinen, F\u00fc\u00dfen, Kn\u00f6cheln, H\u00e4nden oder im Gesicht, h\u00e4ufigeres oder selteneres Wasserlassen, trockene Haut oder Juckreiz, M\u00fcdigkeit, Muskelkr\u00e4mpfe, \u00dcbelkeit und weniger Appetit.<sup>[1]<\/sup><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Eine internationale Leitlinie von KDIGO beschreibt, wie \u00c4rzte eine Blutarmut bei Menschen mit einer langfristigen Erkrankung der Nieren beurteilen.<sup>[2]<\/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-wat-je-waarde-zegt\">Was Ihr eGFR-Wert aussagt<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">Die Richtlinie des Labors<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Labplusarts, das Labor, mit dem BioProfile zusammenarbeitet, verwendet f\u00fcr die eGFR einen Referenzwert von 90 bis 120 ml\/min\/1,73 m2. Einen Wert innerhalb dieser 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>Wert<\/th><th>Was es bedeuten kann<\/th><th>F\u00fcr wen<\/th><\/tr><\/thead><tbody><tr><td>90 bis 120 ml\/min\/1,73 m2<sup>[3]<\/sup><\/td><td>Das Labor nennt einen Wert zwischen diesen Grenzen normal<\/td><td>Messungen bei Labplusarts<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"bp-bm-caption wp-block-paragraph\">Referenzwert von Labplusarts, dem Labor, mit dem BioProfile zusammenarbeitet, f\u00fcr die eGFR (CKDEPI).<sup>[3]<\/sup><\/p>\n\n\n\n<h3 class=\"wp-block-heading\">eGFR zu niedrig<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Eine niedrige eGFR kann darauf hinweisen, dass Ihre Nieren Abfallstoffe zu langsam filtern. Das kann ein Zeichen f\u00fcr eine Sch\u00e4digung der Nieren durch eine Erkrankung der Nieren sein. Ihr Behandlungsteam pr\u00fcft, was Ihr Ergebnis f\u00fcr Sie bedeutet.<sup>[1]<\/sup><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">BioProfile arbeitet an eigenen Zonen pro Wert, von Risiko bis optimal.
