Iron + Total Iron Binding Capacity
Quest
Not offered
Iron and Total Iron Binding Capacity (TIBC) measures the amount of circulating iron and the blood’s capacity to bind iron with transferrin. Together, these tests help evaluate iron status and diagnose conditions such as iron deficiency anemia or iron overload disorders.
- Iron % Saturation The percentage of transferrin (your iron-carrying protein) that's currently occupied by iron — a key marker for detecting iron deficiency or overload.
- Iron, Total Measures the iron circulating in your blood, used along with other markers (like ferritin and TIBC) to evaluate for iron deficiency or overload.
- Total Iron Binding Capacity (TIBC) Total Iron-Binding Capacity — reflects how much transferrin (the iron-carrying protein) is available in your blood, used with iron and ferritin to evaluate iron status.
- Unsaturated Iron Binding Capacity Unsaturated Iron-Binding Capacity — reflects how much additional iron your blood's transferrin could still carry, used with iron and TIBC to assess iron status.

Itraconazole
Labcorp
Not offered
The antifungal drug itraconazole is active in the treatment of aspergillosis, blastomycosis, histoplasmosis, sporotrichosis, and onychomycosis. It is a protein-bound drug and thus has negligible CSF penetration. It may also be utilized in the treatment of systemic candidiasis and cryptococcosis, especially when other drugs are contraindicated or ineffective. The chronic nature of fungal infections demands constant monitoring of itraconazole levels within a patient to ensure that adequate therapeutic levels of the drug are administered, absorbed and subsequently excreted

Juvenile Polyposis Panel (BMPR1A and SMAD4)
Labcorp
Not offered
This test looks for specific genetic changes in the BMPR1A and SMAD4 genes that are linked to Juvenile Polyposis syndrome (JPS). People with JPS have a higher chance of developing colorectal cancer (40-50%) and stomach cancer (up to 21%, especially if they have many polyps in their stomach). They also have a slightly increased risk for cancers of the small intestine and pancreas. Identifying these genetic mutations can help manage and reduce the risk of cancer.
Kappa/Lambda Light Chains, Free with Ratio
Labcorp
Not offered
The Kappa/Lambda Light Chains, Free with Ratio, Serum test measures the amount of kappa and lambda free light chains (FLCs) in the blood and calculates the kappa to lambda ratio. It is used to assist in the diagnosis of plasma cell disorders, including multiple myeloma, primary amyloidosis, monoclonal gammopathy of unknown significance (MGUS), Waldenström’s macroglobulinemia, and related disorders. It is also used to monitor disease activity and treatment [1].
Kidney Profile
Labcorp
Not offered
This test combines two important assessments, the estimated glomerular filtration rate (eGFR) and the urine albumin-creatinine ratio (ACR), to help in the early detection of Chronic Kidney Disease (CKD). It aligns with the National Kidney Foundation's efforts to encourage the use of this profile for early CKD detection. Surprisingly, a study by NHANES (CDC) found that only a small percentage of individuals with reduced kidney function were aware of their condition. This test aims to increase awareness and early diagnosis of CKD.
- Albumin The main protein made by your liver, which helps balance fluids and carries hormones, vitamins, and medications through your blood. Low levels can point to liver, kidney, or nutrition issues.
- Creatinine A waste product from muscle metabolism, filtered by your kidneys. One of the main markers used to assess kidney function.
- Albumin/Creatinine Ratio, Random
- Creatinine, Random
- Estimated Glomerular Filtration Rate Estimated glomerular filtration rate — a calculated estimate of how well your kidneys are filtering waste from your blood, based on creatinine and other factors.
