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.

White blood cells are also called leukocytes. They are made in your bone marrow and are found in your blood and in your lymphatic tissue, which is part of your lymphatic system.<sup>[1]<\/sup><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Lymphocytes come in two main types: B cells and T cells. B cells target viruses, bacteria and toxins that enter your body. Some T cells can clear away your body's own cells, for example cells affected by a virus.<sup>[1]<\/sup><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The test is also called a blood count with differential or a white blood cell differential. A separate test measures the total number of white blood cells in your blood.<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\">Why your lymphocytes matter<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">White blood cells are an important part of your immune system. When you are ill or your body is damaged, they travel through your blood and tissues to where they are needed. There they help your body defend itself.<sup>[1]<\/sup><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The five types of white blood cells do different work. Measuring them separately gives your doctor important information about your health.<sup>[1]<\/sup><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Your doctor can use the test to keep an eye on your health, to look for the cause of your symptoms or to follow how a value changes during care for a condition of the blood.<sup>[1]<\/sup><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">One reason for the test can be that you feel unusually tired or weak, or that you have bruises with no clear cause.<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-wat-je-waarde-zegt\">What your lymphocyte value tells you<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">The usual range<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Labplusarts, the lab BioProfile works with, measures lymphocytes as a count per litre of blood, in 10^9\/l. A widely used handbook for doctors gives 1.5 to 4.0 10^9\/l as the usual range for adults.

The source does not give its own limits for each type of white blood cell.<sup>[1]<\/sup><\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Lymphocytes too low<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">A low number of white blood cells is called leukopenia. It can point to a condition of the bone marrow or the immune system. Certain medicines can also lower the level, such as medicines against bacteria and medicines given as part of care for a serious condition. If your result looks abnormal, your doctor can order extra tests to look for the cause.<sup>[1]<\/sup><\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Lymphocytes too high<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">A high number of white blood cells is called leukocytosis. It can point to a reaction to bacteria or viruses, to inflammation, to a condition in which the immune system attacks the body's own cells, or to a condition of the blood or the lymphatic system. A reaction of your immune system to a substance from outside and certain medicines containing a steroid can also raise the level.<sup>[1]<\/sup><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">BioProfile is working on its own zones for each value, from risk to optimal. A doctor reviews those zones before they appear in your result.<\/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-wat-het-beinvloedt\">What affects your lymphocytes<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">Illness and inflammation<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">When you are ill or your body is damaged, white blood cells go to the place where they are needed. A reaction to bacteria or viruses and inflammation can raise the number of white blood cells.<sup>[1]<\/sup><\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Medicines<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Certain medicines containing a steroid can raise the number of white blood cells.
