Blood Analyzer Puzzle Solutions Solution

The Blood Analyzer puzzles are 3×3 atom-grid terminals in the Care Center. Clicking a node toggles the atoms; turn them all red to solve. There are three specimens on Normal/Standard difficulties and a fourth, Insanity-only one. Solving them unlocks crafting recipes — including a permanent health upgrade.

Where to Find the Analyzers

• Main analyzer: Blood Lab, Care Center East Wing 1F
• Second analyzer: West Wing Office, 2nd floor

All Solutions

Denatured Blood — Blood Lab

• Solution: click the left-middle node once.
• Reward: Handgun Ammo + Hemolytic Injector recipe

Reversible Blood — room next to the Blood Lab

• Requirement: ID Wristband Lv1
• Solution: bottom-left → middle → top-right → 2nd from top
• Reward: Steroids + Stabilizer

Converged Blood — closet south of the Waiting Room

• Requirement: ID Wristband Lv1 (on Insanity this room is the Records Room)
• Solution: top-middle → 2nd square from bottom
• Reward: Med Injector + 12.7x55mm ammo

Polymerized Blood — Insanity only

• Location: same closet as Converged, appears only on Insanity difficulty
• Reward: R.I.P. Knife + Handgun Ammo x30

Why These Puzzles Matter

The Steroids reward from Reversible Blood is a permanent maximum health increase — one of the best upgrades in the game, especially on higher difficulties. The Hemolytic Injector recipe adds a strong craftable healing item.

Common Mistakes

• Clicking the center node on Denatured Blood — the correct single click is the left-middle node.
• Skipping the Waiting Room closet and missing Converged Blood entirely.
• Forgetting that the fourth specimen only appears on Insanity.
