Chloride
The electrolyte that tracks fluid balance and acid-base status, and helps flag metabolic disturbances.
Consider this test if:
- Following up an electrolyte or acid-base abnormality flagged on a prior panel
- Symptoms of fluid imbalance: persistent vomiting, prolonged diarrhea, or dehydration
- Tracking electrolytes while on diuretics or for kidney-related concerns
- Wanting an electrolyte baseline as part of a routine metabolic check
- HSA/FSA eligible
- Typical results in 1 day · Reviewed by a real clinician
- Drawn at a CLIA/CAP-accredited lab near you ·
Pre-test considerations
A routine blood draw. Chloride itself does not require fasting, though it is often drawn alongside glucose or a metabolic panel, in which case a 12-hour fast is requested. Heavy fluid intake or significant dehydration shortly before the draw can shift the result.

What members say on Trustpilot
What this test is for
Chloride is the major negatively charged electrolyte in blood, working alongside sodium and bicarbonate to maintain fluid volume, blood pressure, and the body's acid-base balance. Abnormal levels rarely act alone: high chloride often accompanies dehydration, kidney issues, or a metabolic acidosis, while low chloride shows up with vomiting, certain diuretics, or fluid overload. It is read together with sodium, potassium, and bicarbonate to spot patterns rather than interpreted in isolation. This single chloride measurement is part of the same serum panel logic as the broader Electrolyte Panel (which pairs it with sodium, potassium, and carbon dioxide) and the Basic Metabolic Panel (which adds glucose and kidney markers); choose those if you want the full electrolyte or metabolic picture rather than chloride alone.

Frequently asked questions
View all FAQsHow does pricing work?
Every test shows the member price next to the standard non-member price, so you can see what membership saves you. The member price is our cost — covering the lab and what it takes to run the service — never a profit on the test itself; Mito makes its money on the $9 membership, not on marking up your tests. Membership is $9/mo, and you still pay the lab’s order fee. Prices are itemized before you pay, with no hidden fees.
Where do I get tested?
Choose a partner lab (Quest, Labcorp, or BioReference) at checkout. If your cart spans multiple tests, we consolidate the whole order onto a single lab so you only make one visit.
Is this eligible for HSA/FSA?
Yes. This test is HSA/FSA eligible, and you can pay with your HSA/FSA card at checkout.
When will I get my results?
Your results post to your dashboard once your lab completes them, then a clinician reviews them and your full analysis and personalized action plan (with clear next steps) follow. Turnaround varies by test: specialty assays and at-home kits take longer, and each test shows its expected turnaround before you buy.
Do I need a doctor’s order?
No. Mito provides the lab order for you, so you can book and get tested without a separate doctor visit.
