Match the stool measurement to your symptoms

Each of these answers a different digestive question — a bacterium, parasites, or intestinal inflammation.

Stool tests examine a sample for selected antigens, microscopic findings, inflammatory proteins, or digestive enzymes. People compare these options when persistent digestive symptoms, travel or exposure concerns, or a clinician’s follow-up question calls for a targeted laboratory measurement. H. Pylori Antigen Stool measures Helicobacter pylori antigen, while Ova & Parasites w/Giardia Antigen (Stool) combines Giardia antigen with an ova and parasites concentration and permanent smear. Start by matching the question—H. pylori, parasites, intestinal inflammation, or chymotrypsin—to the measurement that addresses it, then review results with a qualified professional when symptoms or treatment decisions are involved.

Match the measurement to the digestive question

Helicobacter pylori antigen, Giardia antigen, and ova and parasites microscopy answer different organism-related questions. H. Pylori Antigen Stool measures Helicobacter pylori antigen. Ova & Parasites w/Giardia Antigen (Stool) measures Giardia antigen and examines an ova and parasites concentration and permanent smear. For intestinal inflammation questions, Calprotectin, Stool measures calprotectin, while Lactoferrin, Qualitative, Stool and Lactoferrin, Quantitative, Stool focus on lactoferrin. Chymotrypsin, Stool measures chymotrypsin, an enzyme associated with digestive activity. Selecting the named measurement keeps the laboratory question aligned with the concern being evaluated.

Put stool findings in their proper limits

A detectable antigen or a microscopic ova and parasites finding is a laboratory observation, not a diagnosis by itself. A negative result reflects the specific antigen, enzyme, protein, or microscopic examination performed on the submitted sample; it does not account for every possible source of digestive symptoms. Calprotectin and lactoferrin results identify inflammatory proteins in stool, but inflammatory findings require interpretation alongside symptoms and clinical history. Qualitative lactoferrin reports whether lactoferrin is detected, whereas quantitative lactoferrin reports an amount. Review organism-related or inflammatory results with a qualified professional, especially when symptoms persist, worsen, or affect daily activities.

Stool Tests FAQ

A stool test measures a defined finding in a fecal sample rather than providing one universal digestive assessment. Available options measure Helicobacter pylori antigen, Giardia antigen, ova and parasites on concentration and permanent smear, calprotectin, lactoferrin, or chymotrypsin. These measurements address distinct questions about organism-related findings, intestinal inflammatory proteins, or an enzyme associated with digestive activity.

H. Pylori Antigen Stool measures Helicobacter pylori antigen in stool. Detectable antigen is a finding that a qualified professional should interpret with symptoms, history, and other clinical information; it does not establish a diagnosis on its own. This option is more specific to Helicobacter pylori antigen than tests centered on Giardia, Cryptosporidium, ova and parasites microscopy, calprotectin, lactoferrin, or chymotrypsin.

Ova & Parasites w/Giardia Antigen (Stool) combines Giardia antigen with an ova and parasites concentration and permanent smear examination. Giardia and Cryptosporidium Antigen Panel is named for Giardia and Cryptosporidium antigen testing instead. The first option includes microscopic ova and parasites examination, while the latter focuses on the two named antigens. That difference matters when the question specifically includes parasite microscopy.

Calprotectin, Stool measures calprotectin, and the lactoferrin tests measure lactoferrin; both are stool proteins used in intestinal inflammation questions. Lactoferrin, Qualitative, Stool reports a qualitative finding, while Lactoferrin, Quantitative, Stool provides a quantity. A result from either protein needs clinical interpretation because an inflammatory protein finding alone does not identify the cause of symptoms.

Chymotrypsin, Stool measures chymotrypsin, a digestive enzyme in stool. It serves a different purpose from antigen tests for Helicobacter pylori, Giardia, or Cryptosporidium and from inflammatory proteins such as calprotectin and lactoferrin. An enzyme result should be considered with the digestive concern that prompted testing and professional evaluation when symptoms or nutrition concerns are significant.

Giardia Antigen, EIA, Stool is directed at Giardia antigen. Ova & Parasites w/Giardia Antigen (Stool) also measures Giardia antigen, but it additionally includes an ova and parasites concentration and permanent smear. The single-antigen option fits a focused Giardia question, whereas the combined test includes a microscopic parasite examination as well as the Giardia antigen measurement.

No. A negative stool result applies to the particular antigen, protein, enzyme, or microscopic examination performed on the submitted sample. For example, a negative Helicobacter pylori antigen result does not evaluate calprotectin or chymotrypsin, and a negative Giardia antigen result does not replace an ova and parasites microscopic examination. Persistent symptoms deserve professional review even when a selected result is negative.

Start with whether the question is about calprotectin or lactoferrin, because they are separate proteins measured by different tests. Calprotectin, Stool measures calprotectin; Lactoferrin, Qualitative, Stool indicates a qualitative lactoferrin finding; and Lactoferrin, Quantitative, Stool reports an amount of lactoferrin. Inflammatory protein results do not identify a cause by themselves and should be reviewed in light of symptoms and clinical history.
