Methylmalonic acid is produced during human metabolism. Vitamin B12 is required for its further metabolism. If insufficient vitamin B12 is available for this process, the concentration of methylmalonic acid may rise.<br \/>The measurement of methylmalonic acid therefore serves as an indirect laboratory parameter for assessing vitamin B12 status.<\/p>\n<h2>What do the results indicate?<\/h2>\n<p>The lab report provides information on the measured methylmalonic acid concentration and allows for the interpretation of the tested lab parameter in relation to vitamin B12 status. A single lab result should not be used in isolation to diagnose a disease or a vitamin B12 deficiency. If you have abnormal results, health concerns, or questions about how your results apply to you personally, please consult a doctor or other qualified healthcare professional.<\/p>\n<p>[\/et_pb_text][\/et_pb_column][\/et_pb_row][\/et_pb_section][et_pb_section fb_built=&#8221;1&#8243; custom_padding_last_edited=&#8221;on|tablet&#8221; admin_label=&#8221;Produktseite Health Claims 80%&#8221; module_class=&#8221;overflow-hidden claims-container claims-container-80&#8243; _builder_version=&#8221;4.27.6&#8243; _module_preset=&#8221;default&#8221; custom_padding_tablet=&#8221;|1rem||1rem|false|false&#8221; custom_padding_phone=&#8221;20px||0px||false|false&#8221; global_colors_info=&#8221;{}&#8221;][et_pb_row module_class=&#8221;hfinger-producttext-wrapper claims-wrapper&#8221; _builder_version=&#8221;4.27.6&#8243; _module_preset=&#8221;default&#8221; width_tablet=&#8221;100%&#8221; width_phone=&#8221;100%&#8221; width_last_edited=&#8221;on|tablet&#8221; max_width=&#8221;2560px&#8221; custom_padding=&#8221;|0px||0px|false|false&#8221; locked=&#8221;off&#8221; global_colors_info=&#8221;{}&#8221;][et_pb_column type=&#8221;4_4&#8243; module_class=&#8221;claims-wrapper-col&#8221; _builder_version=&#8221;4.27.6&#8243; _module_preset=&#8221;default&#8221; global_colors_info=&#8221;{}&#8221;][et_pb_text module_class=&#8221;claims-text&#8221; _builder_version=&#8221;4.27.6&#8243; _module_preset=&#8221;default&#8221; custom_padding=&#8221;|0px||0px|false|false&#8221; global_colors_info=&#8221;{}&#8221;]<\/p>\n<h2>The test kit contains<\/h2>\n<p>The test kit contains the materials needed to collect and submit the urine sample.<br \/>These include:<\/p>\n<ul>\n<li>Urine collection cup<\/li>\n<li>Test tubes for the urine sample<\/li>\n<li>Shipping materials for returning the sample<\/li>\n<li>Instructions for performing the test<\/li>\n<\/ul>\n<p>[\/et_pb_text][\/et_pb_column][\/et_pb_row][\/et_pb_section][et_pb_section fb_built=&#8221;1&#8243; custom_padding_last_edited=&#8221;on|tablet&#8221; admin_label=&#8221;Produktseite Fullwidth Text 80%&#8221; module_class=&#8221;interim-uebersicht interim-fullwidth-text fullwidth-80&#8243; _builder_version=&#8221;4.27.6&#8243; _module_preset=&#8221;default&#8221; background_color=&#8221;#FFFFFF&#8221; width=&#8221;80%&#8221; width_tablet=&#8221;100%&#8221; width_phone=&#8221;100%&#8221; width_last_edited=&#8221;on|tablet&#8221; max_width=&#8221;1920px&#8221; module_alignment=&#8221;center&#8221; custom_padding=&#8221;4rem||||false|false&#8221; custom_padding_tablet=&#8221;2rem||||false|false&#8221; custom_padding_phone=&#8221;0px||||false|false&#8221; locked=&#8221;off&#8221; global_colors_info=&#8221;{}&#8221;][et_pb_row custom_padding_last_edited=&#8221;off|desktop&#8221; module_class=&#8221;interim-fullwidth-text-container&#8221; _builder_version=&#8221;4.27.6&#8243; _module_preset=&#8221;default&#8221; width=&#8221;100%&#8221; custom_margin=&#8221;2rem||||false|false&#8221; custom_padding=&#8221;|1rem||1rem|false|false&#8221; custom_padding_phone=&#8221;|1rem||1rem|false|false&#8221; global_colors_info=&#8221;{}&#8221;][et_pb_column type=&#8221;4_4&#8243; module_class=&#8221;interim-fullwidth-text-container-row&#8221; _builder_version=&#8221;4.27.6&#8243; _module_preset=&#8221;default&#8221; global_colors_info=&#8221;{}&#8221;][et_pb_text content_tablet=&#8221;<\/p>\n<h2 style=%22text-align: left;%22><sup>rubyni\u00ae<\/sup>, the daily boost for your body<\/h2>\n<\/p>\n<p style=%22text-align: left;%22>With<sup>rubyni\u00ae<\/sup>, we are fully committed to processing high-quality berries and fruits to the highest standards.
